Open markdown files in mdr (md-redline) for human review, or continue an existing review session. To start a new review, pass filePaths. To continue after addressing a batch of comments, or to re-poll while the user is still reviewing, pass the sessionId from the previous result (without filePaths). If the result says the user has not finished yet, call again with the same sessionId to keep waiting. IMPORTANT: while this tool is waiting (no "batch" or "done" result has arrived yet, or you are between batches), you do not have permission to read, open, edit, or otherwise act on the files under review using other tools. The user is actively writing @comment markers into those files; reading them yourself will surface unsubmitted markers you must not address. Once a "batch" or "done" result arrives you may read/edit the files, but only to address the comments listed in that result — ignore any other @comment markers you encounter in the file.
