The SW cache name was hardcoded to 'pinchchat-v1', meaning PWA users would get stale cached assets forever. Now the cache name includes the package version and build timestamp, so each build creates a new cache and old ones are cleaned up on activation. Also adds: - Periodic SW update check (every 30 min) - Auto-reload when new SW version is detected
