VRKA Android 4.0.1 Hotfix

VRKA Android 4.0.1 is an immediate production hotfix addressing YouTube format/quality capping and introducing an on-device Diagnostics UI.

Key Changes & Fixes

1. YouTube Format & Bitrate Resolution:

   • Resolved an issue where YouTube downloads were capped at ~640×360 (format 18) regardless of source resolution (1080p, 4K, HDR, 60fps).
   • Removed aggressive --extractor-args "youtube:player_client=..." that caused SABR streaming fallback and stripped DASH manifests.
   • Restored proper video format selection via buildVideoFormat() (bestvideo+bestaudio/best) and resolution/fps sorting (-S res,fps), enabling full 1080p, 4K HDR 60fps, and high-framerate stream downloads.

2. On-Device Diagnostics UI:

   • Added a dedicated Diagnostics section in Settings to inspect detailed failure records for failed downloads.
   • Captures failure stage (Direct Extraction, Browser Fallback, Native Replay, Gecko Transport, Publishing), error category, error summary, and sanitized terminal log tail.
   • Strictly 100% on-device and private: automatically redacts authorization tokens, cookies, passwords, and sensitive query parameters; zero remote analytics or telemetry.
   • Includes one-tap "Copy Details" for bug reporting and "Clear All" for log management.

3. Cryptographic Signing Continuity:

   • Built and signed with the canonical v1.0 signing key (9befdbf4fb00acedb72f866ce4016944c95ea99448e205768383b310ca11e1fa).
   • Verified seamless in-place upgrade (INSTALL_FAILED_UPDATE_INCOMPATIBLE prevention) over v4.0.0.
