pyproject.toml: Enforce import annotations style

Add new ruff rules and fix their fallout:
future-annotations = true
   select = [
    "TC",  # type-checking import placement rules
    "FA",  # future annotations rules
   ]
This comprises:
- Streamline imports and exports in cmds.xxx.Cmd
    - Import base class as "Base"
    - Export types Cmd and Parent via __all__
- Move all types imported only for annotation below TYPE_CHECKING
- Use "from __future__ import annotations" all over the place
