- Pidfile guard prevents duplicate watchdog instances
- Removed check_zombies — was killing legitimate git push/clone from
active workers (caused mass exit 143 failures)
- Replaced with check_disk that cleans clone dirs >1hr old
- Disabled gemini loop check (no API key configured)
- Workers use fresh clone per issue (no shared worktree contention)
- Simplified cleanup to rm -rf (no git worktree bookkeeping)
- Tested file_issue end-to-end — confirmed working
