Subject: [PATCH] Fix TypeError in child_process.spawnSync wrappers

Update Node.js child_process.spawnSync wrappers in Tracker, GitHub, and Release Day services to defensively handle output objects. `spawnSync` may not always return a standard structure when the process cannot spawn (e.g., ENOENT for an unrecognized command). We now correctly verify types and test for `result.error` directly.
