  The main handler function for the 'get_hot_topics' MCP tool. It is decorated with @mcp.tool(), defines the input schema via Annotated Field, extensive docstring, and delegates to the DiscourseClient via get_client().
  @mcp.tool() def get_hot_topics( page: Annotated[ int | None, Field(default=None, description="Page number for pagination (0-indexed, default: 0)"), ] = None, ) -> list[TopicSummary]: """ Fetch currently trending/hot topics from USCardForum. This returns the most actively discussed topics right now, ranked by engagement metrics like recent replies, views, and likes. Use this to: - See what the community is currently discussing - Find breaking news or time-sensitive opportunities - Discover popular ongoing discussions Args: page: Page number for pagination (0-indexed). Use page=1 to get more topics. Returns a list of TopicSummary objects with fields: - id: Topic ID (use with get_topic_posts) - title: Topic title - posts_count: Total replies - views: View count - like_count: Total likes - created_at: Creation timestamp - last_posted_at: Last activity timestamp Example response interpretation: A topic with high views but low posts may be informational.
