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
- Update notification UI component
This prevents stale cached code from causing white screens by ensuring users always get the latest version after deployment.

- Bumped service worker cache version to v2 to force cache invalidation
- Added activate event to explicitly clear old caches
- Enhanced service worker logging with update checking
- Changed API fallback URL from localhost:3001 to https://puffinoffset.com/api
This fixes the issue where new code deployments were not being used due to
service worker caching the old JavaScript with the timing bug.
