Codex VS Code extension 0.145.x gets stuck in a crash-loop spinner on Linux

What happened
A user reports that the OpenAI Codex VS Code extension enters a perpetual loading spinner on Linux after updating to a 0.145.x-based build.
Symptoms
- The Codex icon appears, but the sidebar never finishes loading.
- The chat UI and prompt box never render.
- Authentication succeeds and backend API calls return 200.
- Plugins sync and telemetry export successfully.
- The extension/webview reconnects and reinitializes every few seconds.
Log clues
- The app-server repeatedly sees initialize, config/read, and thread/list requests on the same connection.
- Extension logs repeat messages like IpcRouter and CodexMcpConnection initialize events.
- One key line says: Received broadcast but no handler is configured method=client-status-changed.
Likely cause
The report suggests a webview / broadcast handler regression rather than an auth or backend outage.
