Implements comprehensive service worker solution with:
- Dynamic versioning using git commit hash or timestamp
- Automatic cache invalidation on new deployments
- Hourly update checks and user notifications
- Network-first caching strategy with 24-hour expiration
- Build automation via prebuild script
