verify_commit previously loaded devices.json/revoked.json and threw
both away, accepting any commit whose stderr contained "GOODSIG" or
"Good signature". This left device registration and revocation as
no-ops: unregistered keys could push, revoked keys kept working.
The fix:
- Build a temp gpg.ssh.allowedSignersFile from devices.json at the
commit, passed via GIT_CONFIG_COUNT/KEY/VALUE env (no global git
config mutation).
- Run git verify-commit --raw and parse SHA256 fingerprint from stderr
regardless of exit code (SSH git outputs the "Good" line even for
keys not in allowed-signers, with "No principal matched" + exit 1).
- Check revoked.json FIRST: reject if committer_ts >= revoked_at;
accept historical commits (committer_ts < revoked_at).
- Reject if fingerprint is not in active devices.json.
- Bootstrap: accept only when BOTH devices.json AND revoked.json are
empty/absent (not just devices.json alone).
Acceptance: 4 integration tests covering the matrix.

- verify-commit command checks signature against devices.json
- generate-hook outputs installable pre-receive script
- Foundation for server-side enforcement
