feat: Add module docs, Enum coercion, tracebacks, and toggle improvements

- Add comprehensive module docstrings across the codebase for better clarity and documentation.
- Refactor Enum classes (e.g., FileType, ConfirmType) to use `_missing_` for built-in coercion from strings.
- Add `encoding` attribute to `LoadFileAction`, `SaveFileAction`, and `SelectFileAction` for more flexible file handling.
- Enable lazy file loading by default in `SelectFileAction` to improve performance.
- Simplify bottom bar toggle behavior: all toggles now use `ctrl+<key>`, eliminating the need for key conflict checks with Falyx commands.
- Add `ignore_in_history` attribute to `Command` to refine how `ExecutionRegistry` identifies the last valid result.
- Improve History command output: now includes tracebacks when displaying exceptions.

+"""
+Defines `Action`, the core atomic unit in the Falyx CLI framework, used to wrap and
+execute a single callable or coroutine with structured lifecycle support.
+
+An `Action` is the simplest building block in Falyx's execution model, enabling
+developers to turn ordinary Python functions into hookable, retryable, introspectable
+workflow steps. It supports synchronous or asynchronous callables, argument injection,
+rollback handlers, and retry policies.
+
+Key Features:
+- Lifecycle hooks: `before`, `on_success`, `on_error`, `after`, `on_teardown`
+- Optional `last_result` injection for chained workflows
+- Retry logic via configurable `RetryPolicy` and `RetryHandler`
+- Rollback function support for recovery and undo behavior
+- Rich preview output for introspection and dry-run diagnostics
+
+Usage Scenarios:
+- Wrapping business logic, utility functions, or external API calls
+- Converting lightweight callables into structured CLI actions
+- Composing workflows using `Action`, `ChainedAction`, or `ActionGroup`
+
+Example:
+    def compute(x, y):
+        return x + y
+
+    Action(
+        name="AddNumbers",
+        action=compute,
+        args=(2, 3),
+    )
+
+This module serves as the foundation for building robust, observable,
+and composable CLI automation flows in Falyx.

+Defines `ActionFactory`, a dynamic Falyx Action that defers the construction of its

+
+This pattern is useful when the specific Action to execute cannot be determined until

+or selecting configuration-aware flows. `ActionFactory` integrates seamlessly with the
+Falyx lifecycle system and supports hook propagation, teardown registration, and

+Key Features:
+- Accepts a factory function that returns a `BaseAction` instance
+- Supports injection of `last_result` and arbitrary args/kwargs
+- Integrates into chained or standalone workflows

+Defines `ChainedAction`, a core Falyx construct for executing a sequence of actions
+in strict order, optionally injecting results from previous steps into subsequent ones.
+
+`ChainedAction` is designed for linear workflows where each step may depend on
+the output of the previous one. It supports rollback semantics, fallback recovery,
+and advanced error handling using `SharedContext`. Literal values are supported via
+automatic wrapping with `LiteralInputAction`.
+
+Key Features:
+- Executes a list of actions sequentially
+- Optional `auto_inject` to forward `last_result` into each step
+- Supports fallback recovery using `FallbackAction` when an error occurs
+- Rollback stack to undo already-completed actions on failure
+- Integrates with the full Falyx hook lifecycle
+- Previews and introspects workflow structure via `Rich`
+
+Use Cases:
+- Ordered pipelines (e.g., build → test → deploy)
+- Data transformations or ETL workflows
+- Linear decision trees or interactive wizards
+
+Special Behaviors:
+- Literal inputs (e.g., strings, numbers) are converted to `LiteralInputAction`
+- If an action raises and is followed by a `FallbackAction`, it will be skipped and recovered
+- If a `BreakChainSignal` is raised, the chain stops early and rollbacks are triggered
+
+Raises:
+- `EmptyChainError`: If no actions are present
+- `BreakChainSignal`: When explicitly triggered by a child action
+- `Exception`: For all unhandled failures during chained execution
+
+Example:
+    ChainedAction(

+Defines `ConfirmAction`, a Falyx Action that prompts the user for confirmation

+
+`ConfirmAction` supports a wide range of confirmation strategies, including:
+- Yes/No-style prompts
+- OK/Cancel dialogs
+- Typed confirmation (e.g., "CONFIRM" or "DELETE")
+- Acknowledge-only flows
+
+It is useful for adding safety gates, user-driven approval steps, or destructive

+- Supports all common confirmation types (see `ConfirmType`)
+- Integrates with `PromptSession` for prompt_toolkit-based UX
+- Configurable fallback word validation and behavior on cancel
+- Can return the injected `last_result` instead of a boolean
+- Fully compatible with Falyx hooks, preview, and result injection

+Defines `FallbackAction`, a lightweight recovery Action used within `ChainedAction`
+pipelines to gracefully handle errors or missing results from a preceding step.
+
+When placed immediately after a failing or null-returning Action, `FallbackAction`
+injects the `last_result` and checks whether it is `None`. If so, it substitutes a
+predefined fallback value and allows the chain to continue. If `last_result` is valid,

+
+This mechanism allows workflows to recover from failure or gaps in data
+without prematurely terminating the entire chain.
+
+Key Features:
+- Injects and inspects `last_result`
+- Replaces `None` with a fallback value
+- Consumes upstream errors when used with `ChainedAction`
+- Fully compatible with Falyx's preview and hook systems

+"""
+Defines `ProcessAction`, a Falyx Action that executes a blocking or CPU-bound function
+in a separate process using `concurrent.futures.ProcessPoolExecutor`.
+
+This is useful for offloading expensive computations or subprocess-compatible operations
+from the main event loop, while maintaining Falyx's composable, hookable, and injectable
+execution model.
+
+`ProcessAction` mirrors the behavior of a normal `Action`, but ensures isolation from
+the asyncio event loop and handles serialization (pickling) of arguments and injected
+state.
+
+Key Features:
+- Runs a callable in a separate Python process
+- Compatible with `last_result` injection for chained workflows
+- Validates that injected values are pickleable before dispatch
+- Supports hook lifecycle (`before`, `on_success`, `on_error`, etc.)
+- Custom executor support for reuse or configuration
+
+Use Cases:
+- CPU-intensive operations (e.g., image processing, simulations, data transformations)
+- Blocking third-party libraries that don't cooperate with asyncio
+- CLI workflows that require subprocess-level parallelism or safety
+
+Example:
+    ProcessAction(
+        name="ComputeChecksum",
+        action=calculate_sha256,
+        args=("large_file.bin",),
+    )
+
+Raises:
+- `ValueError`: If an injected value is not pickleable
+- `Exception`: Propagated from the subprocess on failure
+
+This module enables structured offloading of workload in CLI pipelines while maintaining
+full introspection and lifecycle management.

+"""
+Defines `SelectFileAction`, a Falyx Action that allows users to select one or more
+files from a target directory and optionally return either their content or path,
+parsed based on a selected `FileType`.
+
+This action combines rich interactive selection (via `SelectionOption`) with
+format-aware parsing, making it ideal for loading external resources, injecting
+config files, or dynamically selecting inputs mid-pipeline.
+
+Supports filtering by file suffix, customizable prompt layout, multi-select mode,
+and automatic content parsing for common formats.
+
+Key Features:
+- Lists files from a directory and renders them in a Rich-powered menu
+- Supports suffix filtering (e.g., only `.yaml` or `.json` files)
+- Returns content parsed as `str`, `dict`, `list`, or raw `Path` depending on `FileType`
+- Works in single or multi-selection mode
+- Fully compatible with Falyx hooks and context system
+- Graceful cancellation via `CancelSignal`
+
+Supported Return Types (`FileType`):
+- `TEXT`: UTF-8 string content
+- `PATH`: File path object (`Path`)
+- `JSON`, `YAML`, `TOML`: Parsed dictionaries or lists
+- `CSV`, `TSV`: `list[list[str]]` from structured rows
+- `XML`: `ElementTree.Element` root object
+
+Use Cases:
+- Prompting users to select a config file during setup
+- Dynamically loading data into chained workflows
+- CLI interfaces that require structured file ingestion
+
+Example:
+    SelectFileAction(

+        directory="configs/",
+        suffix_filter=".yaml",
+        return_type="yaml",
+    )
+
+This module is ideal for use cases where file choice is deferred to runtime
+and needs to feed into structured automation pipelines.

+Defines `SelectionAction`, a highly flexible Falyx Action for interactive or headless
+selection from a list or dictionary of user-defined options.
+
+This module powers workflows that require prompting the user for input, selecting
+configuration presets, branching execution paths, or collecting multiple values
+in a type-safe, hook-compatible, and composable way.
+
+Key Features:
+- Supports both flat lists and structured dictionaries (`SelectionOptionMap`)
+- Handles single or multi-selection with configurable separators
+- Returns results in various formats (key, value, description, item, or mapping)
+- Integrates fully with Falyx lifecycle hooks and `last_result` injection
+- Works in interactive (`prompt_toolkit`) and non-interactive (headless) modes
+- Renders a Rich-based table preview for diagnostics or dry runs
+
+Usage Scenarios:
+- Guided CLI wizards or configuration menus
+- Dynamic branching or conditional step logic
+- User-driven parameterization in chained workflows
+- Reusable pickers for environments, files, datasets, etc.
+
+Example:
+    SelectionAction(
+        name="ChooseMode",
+        selections={"dev": "Development", "prod": "Production"},
+        return_type="key"

+Configuration loader and schema definitions for the Falyx CLI framework.
+
+This module supports config-driven initialization of CLI commands and submenus
+from YAML or TOML files. It enables declarative command definitions, auto-imports
+Python callables from dotted paths, and wraps them in `Action` or `Command` objects
+as needed.
+
+Features:
+- Parses Falyx command and submenu definitions from YAML or TOML.
+- Supports hooks, retry policies, confirm prompts, spinners, aliases, and tags.
+- Dynamically imports Python functions/classes from `action:` strings.
+- Wraps user callables into Falyx `Command` or `Action` instances.
+- Validates prompt and retry configuration using `pydantic` models.
+
+Main Components:
+- `FalyxConfig`: Pydantic model for top-level config structure.
+- `RawCommand`: Intermediate command definition model from raw config.
+- `Submenu`: Schema for nested CLI menus.
+- `loader(path)`: Loads and returns a fully constructed `Falyx` instance.
+
+Typical Config (YAML):
+```yaml
+title: My CLI
+commands:
+  - key: A
+    description: Say hello
+    action: my_package.tasks.hello
+    aliases: [hi]
+    tags: [example]
+```
+

+    from falyx.config import loader
+    cli = loader("falyx.yaml")
+    cli.run()

+- Workflow debugging and CLI diagnostics
-filtering, clearing, and formatted summary display.
+- Interactive history browsing or replaying previous runs
+- Providing user-visible `history` or `last-result` commands inside CLI apps
 
-Core Features:
+Key Features:
-- Stores all action execution contexts globally (with access by name).
+- Global, in-memory store of all `ExecutionContext` objects (by name, index, or full list)
-- Provides live execution summaries in a rich table format.
+- Thread-safe indexing and summary display
-- Enables creation of a built-in Falyx Action to print history on demand.
+- Traceback-aware result inspection and filtering by status (success/error)
-- Integrates with Falyx's introspectable and hook-driven execution model.
+- Used by built-in `History` command in Falyx CLI
-
-Intended for:
-- Debugging and diagnostics
-- Post-run inspection of CLI workflows
-- Interactive tools built with Falyx
 
 Example:
     from falyx.execution_registry import ExecutionRegistry as er

+
+Note:
+    The registry is volatile and cleared on each process restart or when `clear()` is called.
+    All data is retained in memory only.
+
+Public Interface:
+- record(context): Log an ExecutionContext and assign index.
+- get_all(): List all stored contexts.
+- get_by_name(name): Retrieve all contexts by action name.

+This module implements `CommandArgumentParser`, a flexible, rich-aware alternative to
+argparse tailored specifically for Falyx CLI workflows. It provides structured parsing,
+type coercion, flag support, and usage/help rendering for CLI-defined commands.
+
+Unlike argparse, this parser is lightweight, introspectable, and designed to integrate
+deeply with Falyx's Action system, including support for lazy execution and resolver
+binding via `BaseAction`.
+
+Key Features:
+- Declarative argument registration via `add_argument()`
+- Support for positional and keyword flags, type coercion, default values
+- Enum- and action-driven argument semantics via `ArgumentAction`
+- Lazy evaluation of arguments using Falyx `Action` resolvers
+- Optional value completion via suggestions and choices
+- Rich-powered help rendering with grouped display
+- Optional boolean flags via `--flag` / `--no-flag`
+- POSIX-style bundling for single-character flags (`-abc`)
+- Partial parsing for completions and validation via `suggest_next()`
+
+Public Interface:
+- `add_argument(...)`: Register a new argument with type, flags, and behavior.
+- `parse_args(...)`: Parse CLI-style argument list into a `dict[str, Any]`.
+- `parse_args_split(...)`: Return `(*args, **kwargs)` for Action invocation.
+- `render_help()`: Render a rich-styled help panel.
+- `suggest_next(...)`: Return suggested flags or values for completion.
+
+Example Usage:
+    parser = CommandArgumentParser(command_key="D")
+    parser.add_argument("--env", choices=["prod", "dev"], required=True)
+    parser.add_argument("path", type=Path)
+
+    args = await parser.parse_args(["--env", "prod", "./config.yml"])
+
+    # args == {'env': 'prod', 'path': Path('./config.yml')}
+
+    parser.render_help()  # Pretty Rich output
+
+Design Notes:
+This parser intentionally omits argparse-style groups, metavar support,
+and complex multi-level conflict handling. Instead, it favors:
+- Simplicity
+- Completeness
+- Falyx-specific integration (hooks, lifecycle, and error surfaces)

+General-purpose utilities and helpers for the Falyx CLI framework.
+
+This module includes asynchronous wrappers, logging setup, formatting utilities,
+and small type-safe enhancements such as `CaseInsensitiveDict` and coroutine enforcement.
+
+Features:
+- `ensure_async`: Wraps sync functions as async coroutines.
+- `chunks`: Splits an iterable into fixed-size chunks.
+- `CaseInsensitiveDict`: Dict subclass with case-insensitive string keys.
+- `setup_logging`: Configures Rich or JSON logging based on environment or container detection.
+- `get_program_invocation`: Returns the recommended CLI command to invoke the program.
+- `running_in_container`: Detects if the process is running inside a container.
+
+These utilities support consistent behavior across CLI rendering, logging,
+command parsing, and compatibility layers.

+Input validators for use with Prompt Toolkit and interactive Falyx CLI workflows.
+
+This module defines reusable `Validator` instances and subclasses that enforce valid
+user input during prompts—especially for selection actions, confirmations, and
+argument parsing.
+
+Included Validators:
+- int_range_validator: Enforces numeric input within a range.
+- key_validator: Ensures the entered value matches a valid selection key.
+- yes_no_validator: Restricts input to 'Y' or 'N'.
+- word_validator / words_validator: Accepts specific valid words (case-insensitive).
+- MultiIndexValidator: Validates numeric list input (e.g. "1,2,3").
+- MultiKeyValidator: Validates string key list input (e.g. "A,B,C").
+
+These validators integrate directly into `PromptSession.prompt_async()` to
+enforce correctness and provide helpful error messages.
