- Add pathspec>=0.12 to root pyproject dependencies (was undeclared, caused
ModuleNotFoundError in CI across all Python versions + Windows)
- Rename drive_test.py -> drive_check.py so pytest stops collecting the module
as a test file; update MODULE_NAME, PRIMARY_COMMAND, help text, README, tests
- 220 backup tests pass, seedgo 100% all 37 standards
