#!/usr/bin/env python3
"""
Update the single spooler file for a message after sending a reply.
One file per message: read the .pending file (same base), add response data and set status to responded, write back.
No separate .response file; no file deletion.
Usage: ./git-issues/write-response-spooler.sh --base <base> --to <addr> --subject "..." --body "..." [--in-reply-to "<msg-id>"]
  base = filename base without extension (e.g. 2026-03-14T094530.a1b2c3d4.user_example.com).
