AAA f92162b3bb feat: launch Piik with a unified interface and public website
Piik now has one public presentation and a coordinated App/Server release path. This phase unifies the room UI, rewrites the bilingual README and guides, adds a static website with an inline product film, and prepares matching GitHub/Gitee packages and update links.

The film uses the current homepage and shared product controls on one seekable timeline. Runtime fixes preserve presentation when the App opens a room, normalize Site origins, and keep capture and media-recovery status in the television indicator. New visits use Chinese for a Chinese system language and English otherwise; explicit language and visual-mode choices remain available. An optional site passphrase controls site entry, while room authorization remains enforced.

GitHub is the release authority. Gitee mirrors verified packages and provides update metadata when GitHub is unavailable. Reviewed PR release notes become the GitHub Release description. The separate public demo uses P2P only, with HTTPS and STUN verified.

Validation: 756 Web tests, TypeScript and production build; Go core tests, formatting, vet and available target builds; bounded Windows capture and App/Site interoperability; browser film checks, audible playback and narrow layouts; anonymous Gitee Windows-package download, checksum and launcher/update-link checks. Public demo acceptance covers authenticated WebSocket signaling, synthetic P2P video and room cleanup on one network. macOS/Linux physical capture and the wider device/network/endurance matrix remain explicitly deferred.

Publication builds every package from the merged source SHA. The repository is public, main protection is active, and Pages is configured for piik.tv. CI/publisher and Pages deployment records own publication results.
