[FEATURE] Interactive mode when run without arguments #55
Description
With the addition of PyInstaller builds, Windows users will likely double-click waybackup-windows.exe expecting it to run. Currently it flashes a console window and exits since CLI arguments are required.
Suggestion: When no arguments are provided, enter an interactive mode that prompts the user for:
- URL to download
- Mode (all/last/first/save)
- Output directory
- Other common options
This would make the tool more accessible, especially for Windows users unfamiliar with the command line.
