Session
Manage sessions, threads, and session wiring. Use when the user mentions sessions, threads, plans, reviews, claims, debriefs, or session sync/doctor. Also triggered by natural language like "create a thread", "what threads are open", "close this thread", "show me the session", "sync the session", "check session health", "claim the frontend thread", "lock the plan", "add a task", or "what's the session status".
