 Notes:
+
 - Each worker receives `CLUSTER_WORKER=true` and `CLUSTER_WORKER_ID=<n>` environment variables.
 - Restart policy uses exponential backoff with jitter and a sliding window threshold to prevent flapping.
 - Defaults: `shutdownTimeout` 30s, `respawnThreshold` 5 within 60s, `restartDelay` 1s, `maxRestarts` 10.
 
 Configuration reference (cluster):
+
 - `enabled` (boolean): enable multi-process mode
 - `workers` (number): worker process count (defaults to CPU cores)
 - `restartWorkers` (boolean): auto-respawn crashed workers
