src/cli,config(fix[workspace-label]): fix workspace resolution for path-first adds

why: Path-first adds should derive workspace from repo parent directory, and handle home directory edge case.
what:
- _resolve_workspace_path returns repo.parent when workspace_root is None
- workspace_root_label handles workspace_path == home to return ~/
- Prevents ~/./  labels when workspace is the home directory
