New worker flow (enabled via USE_SESSION_POOL=true):
1. Worker claims up to 6 tasks for same geo (atomically marked claimed)
2. Gets Evomi proxy for that geo
3. Checks IP availability (not in use, not in 8hr cooldown)
4. Locks IP exclusively to this worker
5. Runs preflight with locked IP
6. Executes tasks (3 concurrent)
7. After 6 tasks, retires session (8hr IP cooldown)
8. Repeats with new IP
Key files:
- migrations/112_worker_session_pool.sql: Session table + atomic claiming
- services/worker-session.ts: Session lifecycle management
- tasks/task-worker.ts: sessionPoolMainLoop() with new flow
- services/crawl-rotator.ts: setFixedProxy() for session locking
Failed tasks return to pending for retry by another worker.
No two workers can share same IP simultaneously.
