"""Append one reply to the newOS4 maintenance thread.
Hermes writes here instead of POSTing to agent-replies.php, so an expired admin cookie can
never make a reply look delivered when it was not. Same JSON schema and file the PHP endpoint
serves to the in-app `feedback-inbox` command.
Usage: newos4-reply.py "Triage 2026-10-23: ..." [--author hermes]
