The old test tests/unit/pkgmgr/actions/test_branch.py has been removed because:
- it targeted the previous monolithic pkgmgr.actions.branch module structure
- its patch targets no longer match the refactored code
- its responsibilities are now fully covered by the new, dedicated unit,
integration, and E2E tests for branch actions and CLI wiring
This avoids redundant coverage and prevents misleading or broken tests
after the branch refactor.
