Address review comments: fix shared_context cleanup and rewrite error test

- Fix comment about .deinit = true in server.zig to clarify it enables automatic cleanup
- Fix shared_context cleanup in ServerWebSocket.onClose() to avoid use-after-free
- Rewrite WebSocket error handler test to use public API instead of accessing ws._socket
- Remove detailed error assertions since error parameter may be undefined

All 17 tests passing.
