feat(player): Add Kick-style Multi-Stream player, stream picker dialog, and live stream resolvers

Summary of Changes

This PR introduces a Kick-style Multi-Stream (MultiView) Player to CloudStream, allowing users to watch multiple live streams or videos simultaneously with interactive layout modes, dynamic volume control, and streamlined stream selection.

Key Features

1. Kick-style MultiView Player (MultiViewPlayerFragment)

   • Supports up to 9 concurrent playback slots.
   • Interactive layout switching: Grid View and 1+2 Focus Mode (main focused stream + side feeds).
   • Dynamic per-stream volume control, mute/unmute toggles, and hover/touch sliders.
   • Graceful offline stream detection and prompt to return to single-player when closing active feeds.

2. Stream Picker Dialog (MultiViewStreamPickerDialog)

   • Instant 0ms local population from active providers, current home section, bookmarks, favorites, and mirror sources.
   • Asynchronous multi-page background scraping and live query execution (live / vs).
   • Real-time search filter across all extensions and category chip filtering.
   • Batch stream selection with live progress indication.

3. Multi-Player Manager (MultiPlayerManager)

   • Multi-slot ExoPlayer instance management, resolution capping, and seamless single-stream <-> multi-stream state transfer.
   • Synchronized audio focus (active focused stream unmuted, secondary streams muted automatically).

4. Code Quality & Compatibility

   • Updated Kotlin ABI reference (library.api).
   • Cleaned up method complexity to satisfy CodeFactor.
   • Compatible with Media3 dynamic range compressor and HW+ decoding pipeline.

Testing & Verification

• Tested multi-stream playback across multiple live providers on mobile and Android TV/emulator layouts.
• Verified ABI check via ./gradlew library:checkKotlinAbi.
• Verified build via ./gradlew app:assemblePrereleaseDebug.
