Problem
Cache helpers (verify/outdated/update/doctor/clean) need more edge-case coverage: empty cache dir, corrupt metadata, missing remote ref, permission errors.
Solution
Add focused unit tests with temporary directories/fixtures. Do not hit the network. Follow existing pytest patterns in packages/create-python-app-core.
