/**
 * Thread management tools: start_thread and send_message_to_thread.
 *
 * Refactored from the original delegate_to_thread — the delegation workflow
 * is now: start_thread(name) → send_message_to_thread(threadId, task).
 *
 * start_thread: ensures an agent session is running on a named thread.
 * send_message_to_thread: queues a message for the target thread's agent.
 *
 * Process lifecycle code (spawning, PID tracking, cleanup) lives in
 * thread-lifecycle.ts.
