VM Service WebSocket connection (ws://127.0.0.1:.../ws) disconnects after a period of inactivity (between 4-20 minutes, variable), causing a pipe crash when hot reload is attempted. This affects both Chrome and Android targets.
The DTD WebSocket ping fix from PR #5828 (v3.124) does not cover the VM Service WebSocket. A similar keepalive ping is needed for the VM Service connection.

ResidentRunner._serviceDisconnected (resident_runner.dart:1405)
WindowsStdoutLogger.writeToStdOut (logger.dart:737)
FileSystemException: writeFrom failed (OS Error: The pipe is being closed, errno = 232)
