#sweep_stale_worktrees! ⇒ Object

Removes agent-owned worktrees whose branch content is already on main. Scans AGENT_WORKTREE_DIRS (e.g. .claude/worktrees/, .codex/worktrees/) under the main repo root. Safe: skips detached HEADs, the caller’s CWD, and dirty working trees (git worktree remove refuses without –force).
