WebSocket traffic logging

Added

Before: WebSocket traffic logging did not exist
After: Mocked browser sockets log traffic

Browser-based mocked WebSocket connections now log opening, closure, errors, and message direction. Message logs include a truncated public payload and byte length, distinguishing handler-originated traffic from actual socket traffic.

In favour

In favour: Logs mocked socket traffic absent from browser developer tools
In favour: Includes payload previews and byte lengths for logged messages

Against

Against: Proxy-wrapped send methods add work to mocked message delivery
