👻 GhostGRAM v0.2.0-alpha — The Media & Search Engine Overhaul

We are thrilled to introduce GhostGRAM v0.2.0-alpha! This update represents a massive technological leap forward, transitioning our Kotlin Multiplatform client from an initial prototype to a feature-complete, high-performance messaging experience.

🚀 Highlights & New Features

📸 Chat Profile & Shared Media Gallery

• Complete Profile Overhaul: View full user and group metadata including Bio, @username, phone numbers, and supergroup descriptions fetched dynamically from TDLib.
• Shared Media Engine: Integrated a 3x3 media gallery, files list, and voice notes browser powered by TDLib's searchChatMessages filtering.
• Instant Jump to Message: Long-press any media item in the profile to jump directly to its exact position in chat history with smooth scroll interpolation.

🔍 Next-Gen Hybrid & AI In-Chat Search

• Hybrid Search Engine: Combines cloud TDLib search with local SQLite Room full-text queries and an automated Russian morphological stemmer (SearchStemmer) for instant substring matching.
• On-Demand Semantic AI Search: Tap the 🧠 AI button to find messages by meaning, context, or slang using Google Gemini (BYOK architecture)—without burning API token quotas on every keystroke.
• Visual Search Highlighting: Matched search queries are highlighted in real-time with vibrant neon styling inside message bubbles.
• Pinned Message Bar: Persistent pinned message banner with one-click animated jump to the pinned message.

🍿 Flagship Media Viewer (GhostMediaViewer)

• Gallery Pager: Seamlessly swipe left/right across all chat media via HorizontalPager.
• Pinch-to-Zoom & Pan: Fluid 1x to 4x scaling with drag panning and quick double-tap zoom/reset.
• Immersive Cinematic HUD: Single-tap to toggle controls with date, author, and counter (3 of 15).
• Direct Downloads: One-tap saving of photos and videos directly to system Downloads on Android and Desktop.

🌊 Real 5-Bit Audio Waveform & Looping Video Stickers

• True Telegram Waveform: Algorithmic bitwise unpacking of TDLib's 5-bit audio samples into dynamic, two-tone Canvas audio visualizers with seek-on-tap.
• Live Playback Timer: Real-time ticking counter (0:04 / 0:18) during audio playback.
• Looping WebM Engine: Transparent hardware-accelerated .webm video sticker playback on Android using native TextureView with zero background artifacts.
• Format Completeness: Full support for static .webp stickers and looping .mp4 GIFs (messageAnimation).

⚡ Performance & Architecture Overhaul

• 🏎️ Frame-Rate Leap: Reduced frame render latency from ~300ms down to ~40ms on complex sticker animations by migrating to hardware-accelerated Airbnb Lottie on Android.
• 📉 VRAM Texture Optimization: Coil downsampling (700x900px) stops 4K screenshots from overloading GPU memory bandwidth during fast scroll.
• 🪚 Massive Refactoring: Eliminated 700+ lines of duplicate code across repositories and screens by extracting TdlibMessageParser, TdlibMediaSender, and custom Compose hooks.
• 🛡️ Production R8 / ProGuard Build: Fully optimized and obfuscated release APK with secured C++ JNI bindings and clean reflection rules.
