codemcp
If and only if the user explicitly asks you to initialize codemcp with
path, you should invoke this tool. This will return instructions which you should

you can invoke this tool.
If the user indicates they want to "amend" or "continue working" on a PR,
you should set reuse_head_chat_id=True to continue using the same chat ID....
