feat: Strategy 8 — enhance phncdn.com network fallback detection

- Log ALL phncdn.com requests (not just .m3u8) to chrome.storage.local
- Reconstruct manifest URLs from segment URL patterns (/videos/{id}/playlist.m3u8)
- Add GOON_GET_PHNCDN_REQUESTS message handler for popup consumption
- Add queryPhncdnRequests() consumer in viewer/index.js
- Integrate reconstructed manifests into scan pipeline (step 1.6)
