Desktop NodeService aborts on Linux when closing app

Description

Closing OpenCode Desktop on Linux can abort the Electron node.mojom.NodeService utility process while local-server cleanup is still running. systemd-coredump then processes a multi-gigabyte core; in one reproduction it reached a 4.7 GB memory peak and failed with No space left on device.

The main process starts asynchronous sidecar cleanup in before-quit, but Electron continues quitting before that cleanup completes. The sidecar also calls process.exit(0) after reporting stopped, so its Electron utility host is not terminated and reaped by the parent.

Plugins

None

OpenCode version

Current dev desktop build

Steps to reproduce

1. Run OpenCode Desktop on Linux and let the local server start.
2. Close the desktop window normally.
3. Check journalctl or coredumpctl after the app exits.
4. Observe the Electron node.mojom.NodeService process terminating with signal 6/ABRT and systemd-coredump processing it.
