itzDownloader Desktop v1.2.3

Performance & Anti-Crash Release

• 🚀 Blazing-Fast Startup Speed (Reduced from 6s to 2-3s): Re-engineered the initialization lifecycle to mirror \itzCut Desktop. Chromium browser and Vite bundle are now launched concurrently with background engine detection, eliminating the 3-second serial block.
• ⚡ Persistent Hardware & GPU Cache: GPU specifications (e.g. RTX 3050 Laptop), CPU specs, and hardware acceleration encoder support (\NVENC, \QSV, \AMF) are cached in \hardware-cache.json, achieving sub-millisecond instant engine verification on startup.
• 🔒 Comprehensive Anti-Crash Click Locks:
  • Initial splash window is completely click-proof and non-interactive (\pointer-events: none !important, \ocusable: false) to prevent DWM drag/close race conditions and access violations.
  • Active operations (core engine installation of yt-dlp/ffmpeg, and application updates downloading/installing) lock all user interactions with a modal overlay and global event capture, safeguarding binary writing and preventing app crashes.
• 🛡️ Authenticode Digitally Signed Release: Both the NSIS Setup installer and standalone Portable executables are fully signed with RFC 3161 timestamping.
