- Add cors middleware to example servers with Mcp-Session-Id exposed
- Add CORS documentation section to README
- Configure minimal CORS settings (only expose required headers)
This enables browser-based clients to connect to MCP servers by properly
exposing the Mcp-Session-Id header required for session management.

nullish coalescing operator ?? instead of the logical OR operator || to handle the case where this?._eventSourceInit?.fetch or this._fetch might be null or undefined but not falsy

* Returning undefined from `discoverOAuthMetadata` for CORS errors
This behaviour was already happening for the root URL, but the new `fetchWithCorsRetry` logic differed.
The issue was if the server returns a 404 for `/.well-known/oauth-authorization-server/xyz` that didn't have the `access-control-allow-origin`, a TypeError was being thrown. There was logic there already to handle a TypeError for a _preflight_ request (cause by custom headers), but not the fallback. I refactored so all combinations return `undefined`.
* Add test for CORS error handling that should return undefined
This test covers the scenario where both the initial request with headers
and the retry without headers fail with CORS TypeErrors. The desired
behavior is to return undefined instead of throwing.
