- Expanded help command to accept:
- `-k/--key` for detailed help on a specific command
- `-t/--tag` for tag-filtered listings
- `-T/--tldr` for quick usage examples
- Updated TLDR flag to support `-T` short form and refined help text.
- Improved `_render_help()` to show contextual CLI tips after help or TLDR output.
- Adjusted completer to yield both upper and lower case completions without mutating the prefix.
- Standardized CLI tip strings in root/arg parsers to reference `help` and `preview` subcommands instead of menu `run ?` syntax.
- Passed `options_manager` to history/help/exit commands for consistency.
- Allowed `help_command` to display TLDR examples when invoked without a key.
- Added test assertions for help command key/alias consistency.
- Bumped version to 0.1.82.
