Quick Explorer v0.1.23

✨ Folder Size Intelligence & System Branding

• ⚡ Asynchronous Folder Sizes: Implemented a high-performance background engine using Rayon parallelism to calculate folder sizes without affecting UI responsiveness.
• 🛡️ Persistent Folder Cache: Calculated sizes are now saved in localStorage (TTL 2h), allowing them to appear instantly when revisiting folders.
• 🧠 Intelligent Invalidation: Added targeted cache clearing for Move, Copy, Delete, and Rename operations, ensuring sizes stay fresh without unnecessary re-calculations.
• 🟦 System Drive Identity: The system drive (C:) now features a premium, enlarged Windows 11 logo in both the Sidebar and "This PC" views.
• ⚙️ Toolbar Customization: New setting in Ajustes > General to choose between Dynamic (auto-collapse) and Compact (icons only) toolbar modes.
• 🎨 Refined Clipboard UI: Modernized the "Paste" indicator with a cleaner, theme-accented chip design.
