Describe the Bug

Observed behavior

When running a local server via wrangler dev, breakpoints are hit once after the application starts, and then the program immediately resumes and never hits a breakpoint again, indicating a failure in the debugger code

When running with wrangler dev with --log-level debug, the following stack trace was observed, indicating a websocket message greater than 1MB was sent

workerd/jsg/util.c++:281: error: e = kj/compat/http.c++:5754: failed: WebSocket protocol error; protocolError.statusCode = 1009; protocolError.description = Message is too large: 1498317 > 1048576

}
[InspectorProxyWorker] 'runtime websocket' error {
  message: 'internal error',
  name: 'Error',
  stack: 'Error: internal error'
}

Expected behavior

The debugger feature works correctly

Steps to reproduce

This is failing for my code with just wrangler dev

Unclear what message is causing the debugger to choke, but it seems like it's related to sending code or source code over the websockets

debugger still broken on wrangler 3.59.0 3 months later :(

This should be addressed by https://github.com/cloudflare/workerd/commit/fc77758796a0cb0b416cc8c609c054c3bad4dad4, which we'll need to add locally
