"""Sentinel script: check if a user message should re-engage the ml-intern harness.
This is a Codex-plugin workaround for the lack of persistent event hooks.
The harness SKILL.md instructs Codex to run this before each response when
harness mode is active. If the output is RE-ENGAGE, Codex stays in harness mode.
If FREE, it may drop to generic behavior (unless the conversation history shows
prior harness activity).
