Authentic Auris Liquid Glass Floating Navigation Bar (AurisGlassNavBar)

1. Authentic Auris Liquid Glass Floating Navigation Bar (AurisGlassNavBar)
   Stadium Capsule Pill Design: Replaced the traditional flat bottom navigation bar with a centered floating capsule pill with 999dp rounded corners.
   Traveling Selection Lens: Implemented an animated active tab pill indicator with a coral-red gradient (#E02553 to #FB7185) that glides between Home, Search, and Library tabs with realistic spring overshoot physics.
   Specular Hairline Rim Highlight: Added an ultra-fine 0.5dp to 1.0dp translucent border catching light along the edges for an authentic liquid glass appearance.
   Dynamic Typography and Contrast: Active tab icons and titles render in high-contrast crisp white, while inactive tabs use soft muted gray.

2. Redesigned Floating Mini Player (layout_mini_player.xml)
   Matching Stadium Capsule Card: Positioned as a floating pill hovering above the navigation bar with translucent glass background and specular border.
   Curved Square Artwork Thumbnail: Replaced circular cropping with a sleek 10dp rounded square artwork thumbnail matching Auris aesthetics.
   Streamlined Touch Controls: Direct play/pause and skip next action targets on the glass surface.
   Integrated Bottom Progress Bar: Pinned a subtle track progress indicator running smoothly along the bottom curve of the pill.

3. Now Playing Screen Polish (MusicOverviewActivity)
   Eliminated Background Artifacts: Removed unclipped square backdrop views behind artwork that caused visible rectangular line artifacts.
   Stable Artwork Presentation: Kept the primary album artwork card elevated with 20dp rounded corners and subtle drop shadows.
   Removed 1-Second Breathing Jitter: Fixed the 1000ms loop animation reset so album artwork remains rock-solid during playback without micro-stutters.

4. Library and Playlists Modernization
   Modernized list cards with rounded corners and consistent padding.
   Fixed cover art recycling in playlist rows so track art updates immediately upon track change.
   Added automatic "Liked Songs" playlist creation and prompt on song favorites.

5. Tactile Haptic Feedback (HapticUtil)
   Added subtle system haptic feedback on navigation tab clicks, mini-player transport actions, and playback controls.

6. Build and Performance Optimizations
   R8 / ProGuard Minification: Fully enabled code shrinking, obfuscation, and unused resource stripping via assembleRelease.
   Signed Release Package: Added debug keystore fallback for local and CI release builds to guarantee that release APKs install cleanly on Android devices.
