Audio Engine, Discord RPC & Reliability Overhaul

This release is a major under-the-hood upgrade focused on audio quality, rich presence stability, playback reliability, and infrastructure hardening.

Added

• Appearance Settings & Theme Context: A new ThemeProvider enables dynamic accent color selection and layout density modes (Comfortable/Compact/Cozy), all persisted via electron-store.
• Home Page Redesign: New Home view with curated section layouts, responsive card grids, and compact-mode density support.
• Custom NSIS Installer: A custom Windows installer script with user-selectable post-install options: create desktop shortcut, launch on startup, open immediately.
• yt-dlp Auto-Updater: The app automatically checks for yt-dlp binary updates once per day on startup. A manual "Check for Updates" trigger is also exposed in the Settings UI.
• yt-dlp Auto-Repair: If the yt-dlp binary becomes corrupted (e.g. PyInstaller decompression failure, exit code 4294967295), the app now automatically detects this and downloads a fresh binary from the official GitHub releases to self-heal — no manual intervention required.
• YouTube Cookie Harvesting: The main process silently opens a hidden browser partition to harvest fresh YouTube session cookies and passes them to yt-dlp, improving stream fetch success rates and bypassing some geo-restrictions.
• Audio Output Device Switching: The player now supports switching the audio output device at runtime via setSinkId, allowing users to route audio to any connected speaker or headset.
• Playback Speed Control: Real-time playback speed adjustment exposed through settings and applied directly to the HTML audio element.
• Structured Data & SEO: Added schema.org structured data, robots.txt, and sitemap.xml for better discoverability.

Changed

• yt-dlp Multi-Client Fallback: Stream fetching now tries multiple YouTube player clients (mweb, default) in sequence. If the primary client is blocked, the app silently falls back instead of failing.
• Streaming Handler Robustness: Enhanced retry logic, in-memory URL caching (30 min TTL), and deduplication of concurrent fetches for the same track ID. Multiple components requesting the same stream now share a single network request.
• Autoplay Radio Pool: The AutoplayQueue radio pool system now seeds from the tail of the queue for better continuity, shuffles candidates immediately, and de-duplicates by recent artist history for variety.
• Close-to-Tray Behavior: The window close event is intercepted and the app hides to tray by default, with user-configurable option to close outright.
• Improved RPC Stability: Discord RPC now handles connection failures gracefully with a proper retry strategy. An unresponsive or absent Discord client no longer throws unhandled errors.
• PlayerBar Enhancements: Improved player bar UI interactions, state synchronization, and progress bar sizing.

Fixed

• yt-dlp Binary Corruption (Critical): Fixed a crash-to-desktop bug affecting all users where a corrupted yt-dlp.exe triggered a Windows stack-buffer-overrun error (0xC0000409). The PyInstaller bootstrap was failing to decompress internal modules. The app now auto-repairs by re-downloading a clean binary from GitHub — no manual fix required.
• Ghost Song / Audio Bleed: Fixed a race condition where rapidly skipping tracks would leave the previous track's audio element playing beneath the new one. The audio element source is now force-cleared and reloaded on every track change.
• Memory Leak in Prefetch Map: The audio URL prefetch cache is now bounded and auto-pruned to 5 entries, preventing long listening sessions from leaking RAM.
• Audio Graph CPU Waste: The AnalyserNode is now only connected when Volume Normalization is active, preventing unnecessary DSP computation during normal playback.
• CPU Drain on Normalization: The normalization interval is now properly cleaned up when normalization is disabled or the track is paused, stopping a background polling loop that ran indefinitely.
