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
