fix: correct MCP citation links and add DiscussionPanel tests

- DiscussionPanel: update MCP link to anthropic.com/engineering/code-execution-with-mcp
- DiscussionPanel: update Cloudflare link to blog.cloudflare.com/code-mode-mcp/
- Add DiscussionPanel.test.tsx covering title, badge, onClose, hosted-automation
  detail, and mcp-agent-scale link targets
