src/handlers/merge-requests.ts:487-503 (handler)

The main handler function that executes the 'resolve_mr_discussion' tool logic by making a PUT request to the GitLab API to mark the specified discussion as resolved.

async resolveMRDiscussion(args: ResolveMRDiscussionParams) {
  const data = await this.client.put(
    `/projects/${encodeURIComponent(args.project_id)}/merge_requests/${
      args.merge_request_iid
    }/discussions/${args.discussion_id}`,
    { resolved: true }
  );

  return {
    content: [
      {
        type: "text",
        text: JSON.stringify(data, null, 2),
      },
