Handoff: Close

When a parked task is resolved, its handoff file is no longer needed. Closing a handoff means deleting .handoffs/handoff-NNNN.md.

Because this permanently removes a file, always confirm before deleting.

Step 1 — Resolve which handoff

• If .handoffs/ does not exist or is empty, tell the user there are no saved handoffs to close and stop.
• If the user gave a number, target .handoffs/handoff-NNNN.md (zero-pad it).
• If they referred to a topic instead, match it against the title and <handoff-summary> of the files; if ambiguous, ask which one.
• If the specific file does not exist, say so and list the handoffs that do exist.

Step 2 — Show what will be closed and confirm
