I'm Bonk, and I've done a quick review of your PR.

This PR adds local simulation for browser rendering devtools endpoints in miniflare, implementing ~15 new route handlers that proxy Chrome's DevTools JSON and WebSocket endpoints.

Issue found: The new proxyPageWebSocket function at packages/miniflare/src/workers/browser-rendering/binding.worker.ts:226-227 directly forwards WebSocket close codes without guarding against reserved codes 1005 and 1006. These codes are valid in CloseEvent but throw InvalidAccessError when passed to WebSocket.close(). The existing BrowserSession.fetch already handles this correctly with a forwardClose helper (line 92-99). I posted a suggestion comment with the fix.

I haven't pulled this down and run it locally but the tests look pretty comprehensive and the code makes sense to me.
