Automated tunnel recovery supervisor verified and tested under cloud-uptime/uptime-watcher.sh. Implemented: 1) 120s poll loop with file locking, 2) automatic provisioning check via recover-after-rebuild.sh, 3) gcp-tunnel supervisor auto-respawn, 4) persistent crontab restoration, 5) VM SSH forward banner probe, 6) rate-limited failure escalation. Added automated tests in tests/test_uptime_watcher.py (3/3 pass). Full key test suite 62/62 green. Committed to branch builder/tunnel-recovery-supervisor (87be6ae).
