      "message": "  Migrate GitHub Actions caching to Google Cloud Storage.\n\n  This change replaces the use of actions/cache@v4 with custom steps that leverage Google Cloud Storage (GCS) for caching build artifacts. Specifically, this involves:\n  - Adding custom PowerShell and Bash scripts to search for fallback cache keys, download tarball archives from a GCS bucket (gs://litert-lm-cicd), and extract them.\n  - Replacing the cache save steps across all workflows (Windows, Linux, Android) with custom scripts to compress and upload artifacts to GCS via the gcloud CLI.\n  - Utilizing implicit credentials from the custom runner environments (`linux-x86-c4-16` and `windows-x86-n2-16`) and explicitly installing the Google Cloud SDK, replacing the previous Workload Identity Federation authentication approach.\n\nLiteRT-LM-PiperOrigin-RevId: 936696499\n"
