feat: inject start_name/middle_name/end_name as computed keys in API

Instead of a separate node, _get_data now appends three derived keys
to every sequence response: Path(start frame path).stem → start_name,
etc. Any ProjectKey node can use these directly as key_name.

Reverts ProjectFrameNames node (unnecessary).
