Add standalone encryption/decryption scripts with cross-platform support
- Add decrypt/encrypt scripts for macOS, Windows, and Linux - Add cross-platform Python script (decrypt_folder.py) - Update README with setup instructions for all platforms - Scripts support all file types: png, jpg, jpeg, webp, gif, mp4, avi, mov
