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
