Quick Explorer v0.1.25

✨ Grid Performance & High-Fidelity DnD

• 🖱️ Grid DnD Fix: Resolved a critical SecurityError (Tainted Canvas) that prevented dragging files with thumbnails in Grid Mode. The app now performantly fetches thumbnails manually to ensure stable drag initiation.
• ⚡ Instant Thumbnail Loading: Removed the 300ms observer delay in Grid Mode. Thumbnails now load with 0ms latency, providing a truly "instant" visual experience.
• 🔵 Thumbnail Source Indicators: Integrated visual cues (blue/orange dots) to differentiate between native Windows thumbnails and FFmpeg-generated ones, available in both Grid View and Info Panel.
• 📜 Maximized Scroll Fluidity: Increased grid overscan to 5 rows, ensuring that neighboring items are pre-rendered and thumbnails pre-loaded before they enter the viewport.
• 🛠️ Diagnostic Cleanup: Removed all internal DND tracing logs for a cleaner production console.
