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
