feat(help & spinners): improve help rendering, async spinner handling, and pipeline demo

- Refactored `Command.help_signature` to return `(usage, description, tags)` instead of a Rich `Padding`/`Panel`.
- Replaced `show_help()` with `render_help()` in `Command` and `Falyx`.
- Updated Falyx help rendering to use Rich `Panel`/`Padding` consistently for cleaner UI.
- Swapped `print()` calls for `console.print()` for styled output.
- Added hooks to `ProcessAction` to announce analysis start/finish.
- Added spinners to test and deploy steps; simplified retry setup.
- Converted `remove()` to `async def remove()` for consistency.
- Added async lock to prevent concurrent Live loop start/stop races.
- Added debug logging when starting/stopping the Live loop.
- Updated `spinner_teardown_hook` to `await sm.remove(...)` to align with async `remove()`.
- Removed `rich.panel`/`rich.padding` from `Command` since panels are now built in `Falyx` help rendering.
- Bumped `rich` dependency to `^14.0`.
- Bumped version to 0.1.78.

This commit polishes help display, demo UX, and spinner lifecycle safety—making spinners thread/async safe and help output more structured and readable.
