HoneyandClaude Sonnet 4.6 08d2f69720 fix: SW must not intercept cross-origin requests (backend API calls)
Added same-origin check so the SW only caches its own static assets.
Cross-origin requests (Navidrome API, NovaSonic backend) pass through
directly — SW interference was causing 'failed to fetch' in the PWA.
