Store reference to original close method before overriding to prevent stack overflow when closing the server.

I have seen the same error in Kilo Code (VS Code Extension):

file:///home/gero/.npm/_npx/6ddf87659f2ad8a4/node_modules/@browsermcp/mcp/dist/index.js:248 server.close = async () => { ^ RangeError: Maximum call stack size exceeded at server.close

After manually applying the fix #130 , the mcp could load without any problem.

Please merge the fix. Without that browserMCP can not work with Kilo Code
