Add WebSocket workaround test and enhance connection handling

- Introduced a new test file `workaround_test.go` to validate the behavior of a "dumb" WebSocket client that does not handle ping/pong messages correctly, ensuring the connection remains alive through server-side workarounds.
- Updated the `handle-websocket.go` file to improve message size handling and refactor ping/pong logic, allowing for direct message sending and better error management.
- Enhanced the `listener.go` file to support a more robust write channel mechanism, allowing pings to interrupt writes and improving overall connection management.
- Bumped version to v0.23.4 to reflect these changes.
