NodeWorker

Parent-side Node.js support for Effect workers.

layerPlatform installs the WorkerPlatform used by a Node program that owns workers. It supports both node:worker_threads workers and IPC-enabled child processes, routing messages through Effect's worker protocol. layer combines that platform with a Spawner callback, and the platform asks workers to close on scope finalization before forcefully terminating them on timeout.
