refactor: align routing internals and refresh framework docstrings

Browse Source 
- rename several Falyx and Command internal helpers with leading underscores
- rename parallel terminology to concurrent across ActionGroup and SharedContext
- update completer and routing references to match current routed API names
- add and revise module, class, and method docstrings across core modules
- refresh package copyright headers for 2026

`ExecutionOption` is used by Falyx components such as `Command` and

Unlike `CommandArgumentParser`, this module does not parse command-specific
arguments or attempt to resolve leaf-command inputs. Its responsibility is
intentionally narrow: identify root-level flags, determine the initial
application mode, and normalize the result into a `RootParseResult`.
Parsing behavior is prefix-based. Root flags are consumed only from the start of
argv, and parsing stops at the first non-root token or an explicit `--`
separator. This allows the remaining arguments to be preserved exactly for later
namespace resolution and command-local parsing.
Typical flow:
1. Raw argv is passed to `FalyxParser.parse()`.
2. Leading root/session flags are extracted into `RootOptions`.
3. A `RootParseResult` is returned with either:
- `FalyxMode.HELP` when root help or TLDR was requested, or
- `FalyxMode.COMMAND` when normal routed execution should continue.
4. Remaining argv is forwarded unchanged to the main Falyx routing layer.
This module serves as the root-entry parsing boundary for Falyx applications.

mode, and return a normalized `RootParseResult`.
Responsibilities:
- parse global/root flags
- resolve built-ins vs registered commands
- normalize CLI input into ParseResult
- delegate command-specific parsing to CommandArgumentParser
- Parse only root/session flags such as verbose logging, help, TLDR,

- Preserve the remaining argv exactly for downstream routing.
- Translate root help or TLDR requests into `FalyxMode.HELP`.
- Translate normal execution into `FalyxMode.COMMAND`.
Design Notes:
- This parser does not resolve commands or namespaces.
- This parser does not parse command-specific arguments.
- Command-local parsing is delegated later to `CommandArgumentParser`
after Falyx routing has identified a leaf command.
- Root parsing is intentionally prefix-only so session flags apply at
