The MCP server was setting up event listeners on connect but never cleaning up after request handling, causing Cloudflare Workers to detect dangling async operations and cancel requests with a "hung" error. Added server.close() in a finally block to ensure proper cleanup after each request. Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

Summary
Fixed the issue where Cloudflare Workers were hanging with "Worker's code had hung and would never generate a response" errors. The MCP server was setting up event listeners on connect but never cleaning up after request handling, leaving dangling async operations that Cloudflare detected and canceled.
