Native Telegram Integration + ABI Split APKs

Telegram Integration

Adds a built-in Telegram source that searches the user's joined channels and groups for video files whenever a movie or episode is selected — appearing alongside regular addon sources in the stream selector. No third-party service or external addon required.

Authentication

• QR code flow via TDLib (authorizationStateWaitQrCodeConfirmation) — scan with the Telegram phone app, no typing on TV
• 2FA password support
• Session persists across app restarts

Streaming

• Local Ktor CIO HTTP server proxies TDLib file downloads to ExoPlayer with Range header support for seeking

Settings Screen

• Shows connected account name or "Not connected"
• Per-channel toggle to exclude channels from search
• Disconnect button wipes session and TDLib database

Source Card

• Quality parsed from filename (4K, 1080p, 720p, etc.) including OCR typos (1o8o, 216o)
• File size displayed

Native Libraries

• TDLib prebuilt binaries downloaded automatically on first build via downloadTdlibNatives Gradle task
• Cached — re-download only on clean checkout

ABI Split APKs (Sideload)

assembleSideloadRelease now produces per-ABI APKs instead of one universal APK, so users download only the native library for their device architecture.
