Module worker_pool 

WorkerPool — manages N Bun render-pool workers.

Responsibilities:

• Spawn N workers (default = num_cpus / 2, min 1) on a manifest.
• Watchdog task: ping every 30 s; kill + respawn on missed pong.
• Rolling reload: spawn parallel new pool, drain old.
• get(): returns any live worker (round-robin in P9+; index 0 in P7 since Mode 2 is stubbed and no concurrent renders flow through).

Structs

Functions

rolling_reload

Spawn a new pool from fresh manifest bytes and then drain the old pool. The caller swaps the Arc<WorkerPool> reference atomically before draining.
