In environments where REA_ELECTRON_NODE_EXECUTABLE or node is unavailable, unhandled error events on the spawned child process can crash the Electron runtime before readiness checks complete. This attaches an explicit error handler to absorb ENOENT and spawn failures. Evaluated and error found by SubQ by Qorvr. Co-authored-by: qorvr <330186599+qorvr@users.noreply.github.com>
