Add new options

1. Native Windows Style: I've completely removed the dark "fake" style I put in before. The panel will now use your system's native theme (Windows Explorer colors, borders, and fonts). It will look integrated and natural.
2. Functional Explorer:
3. Double-click: Now open the file directly (for example, with VLC or Windows Media Player).
4. Actual Context Menu: I've added key options that you expect in a browser:
5. 📁 Show in Explorer: Takes you directly to the actual folder on Windows.
6. ▶️ Open: Open the file.
7. 🗑️ Delete: Allows you to delete files (with security confirmation).
8. ✏️ Rename: The renamed feature we already had.
9. Drag & Drop: I've turned on the ability to drag files from the panel out (useful if you want to drag a video into Premiere or Discord).
