monitor

Monitor existing Codex child threads with a lead monitor and optional watcher subagents. Use when the user asks to monitor, check progress, get status, wait on child sessions, inspect dispatched work, decide whether a child is clean, send steering or wrap-up instructions, push/deploy/close after a child finishes, supervise multiple Codex worktree sessions, or use a dispatch ledger. Do not use for creating new sessions; use dispatch for that.
