feat(spinners): integrate SpinnerManager and per-action spinners into Falyx

- Added new `SpinnerManager` module for centralized spinner rendering using Rich `Live`.
- Introduced `spinner`, `spinner_message`, `spinner_type`, `spinner_style`, and `spinner_speed` to `BaseAction` and subclasses (`Action`, `ProcessAction`, `HTTPAction`, `ActionGroup`, `ChainedAction`).
- Registered `spinner_before_hook` and `spinner_teardown_hook` automatically when `spinner=True`.
- Reworked `Command` spinner logic to use the new hook-based system instead of `console.status`.
- Updated `OptionsManager` to include a `SpinnerManager` instance for global state.
- Enhanced pipeline demo to showcase spinners across chained and grouped actions.
- Bumped version to 0.1.77.

This commit unifies spinner handling across commands, actions, and groups, making spinners consistent and automatically managed by hooks.
