src/cli(refactor[add]): remove conditional normalization for path-first adds

why: normalize_workspace_roots was only needed for legacy name+URL flow cleanup; path-first adds derive correct labels directly.
what:
- Remove normalize_workspace_roots call from merge path
- Remove in-place label normalization from no-merge path
- Remove unused normalize_workspace_roots import (ruff auto-fix)
- Simplify config_was_relabelled tracking
