 * `peaks worktree gc` — sweep released/expired leases.

 * Extracted verbatim from `worktree-lease-commands.ts` (mechanical move of
 * the `.action()` body). The per-lease sweep is now `sweepLease`; the
 * `--lease-id` / `--dry-run` semantics, the expired-active transition, the
 * best-effort git removal + prune, the per-lease metric emit and the
 * ok/fail envelopes are unchanged.
