- Replace automation service with emergency rate-limited version
- Add 5-minute minimum interval between automation starts
- Implement forced Chromium process cleanup on stop
- Backup broken automation service as .broken file
- Emergency service prevents multiple simultaneous automations
- Fixed 1400+ Chromium process accumulation issue
- Tested and confirmed: rate limiting works, processes stay at 0
