Node.js Multi-Agent Task Supervision: Process Isolation and Heartbeats

As AI-powered background agents become standard fixtures in production Node.js systems, the gap between "spawn and forget" prototypes and supervision that detects failures and kills stuck workers within a bounded timeout keeps growing. A Node.js multi-agent supervisor daemon that combines process isolation, IPC heartbeat monitoring, timeout-driven termination, and concurrency token buckets prevents long-running, unpredictable agent workloads from destabilizing the host process.
