New tool: message response composer

[pavel-kirienko]

Given an external message, received either via email or from the forum, including all preceding conversation context, compose and return the response (possibly with attachments). To compose the response, the tool will run its own LLM with tools for accessing the email, Google Drive, the wiki, the forum, plus possibly asking questions on slack via another tool. Once the response is ready, it is returned back to be submitted. The response may have to be graded by a separate LLM to decide if it needs to be vetted by a human prior to submission.
