Mirrors the CI-green safeguards rolled out repo-wide (see screen-locker):
- scripts/check_requirements_sync.py: pre-commit hook that fails if a
package import isn't declared in requirements.txt. On rollout it caught
a real latent gap — aiohttp is imported by hltb/protondb modules but was
only present transitively (via howlongtobeatpy); now declared explicitly.
- scripts/ci_mirror.sh: pre-push gate = requirements.txt-only venv
(hash-gated) running `pre-commit run --all-files` + `pytest`, replacing
the plain pytest-coverage pre-push hook. The web vitest pre-push hook is
left untouched.
Verified: mirror green (960 passed, 100% cov).
