feat: Add per-app architecture selection and multi-arch downloads

Introduces the ability to specify and download multiple architectures for a single application.

- Adds an "Architecture" dropdown column to the Winget UI, allowing users to select the desired architecture(s) for each app (e.g., x86, x64, arm64, or 'x86 x64').
- Updates the download logic to process each specified architecture, creating separate subfolders for multi-architecture Win32 apps.
- Modifies the app list format to save and load the selected architecture for each application.
- Improves the download process by checking if an application has already been downloaded before attempting a new download.
