## CPU-Intensive Workers guide

New dedicated docs page for handling CPU-heavy jobs over TCP
- Explains the ping health check failure chain that causes job loss after ~90s of CPU load
- Connection tuning: `pingInterval: 0`, `commandTimeout: 60000`
- Non-blocking CPU patterns with `await Bun.sleep(0)` yield
- Default timeouts reference table
- SandboxedWorker as alternative for truly CPU-bound work

## CPU stress test script
