feat: refine menu lifecycle handling and make bottom bar optional

- Allow `bottom_bar` to be `None` in `Falyx` initialization and validation logic.
- Updated error messaging to reflect `None` as a valid bottom bar state.
- Set `FalyxMode.MENU` explicitly when entering interactive menu mode.
- Simplified `menu()` loop by removing unnecessary `asyncio.create_task` wrapping.
- Added `always_start_menu` flag to `run()` to allow returning to the menu after CLI execution.
- Prevent forced `sys.exit()` when `always_start_menu=True` is provided.
- Bumped version to 0.1.86
