Implemented a better multi-link experience.

What I changed

Torrent link handling: If a torrent has 1 link, “Get Link” immediately copies the unrestricted URL (existing behavior). If it has >1, clicking “Get Links” opens a modal where you can:
Copy all unrestricted links at once
Copy any individual unrestricted link
See file names when available; falls back to “File N” if names can’t be resolved

Enhanced Permission & Error Handling:
Added clipboardRead permission for clipboard functionality
Smart validation - Only processes valid magnet links
Helpful notifications guide users on proper usage
Robust error handling for clipboard access issues
Usage Instructions:
Method 1: Right-click directly on the magnet link
- Should now show "Add magnet link to Real-Debrid"
- Click it to add the magnet
Method 2 (if Method 1 doesn't work due to website JS):
- Copy the magnet link (Ctrl+C or right-click → Copy Link)
- Right-click anywhere on the page
- Select "Add magnet from clipboard"
Method 3: Select the magnet link text and right-click
- Highlight the full magnet:?xt=urn:btih:... URL
- Right-click and select "Add magnet link to Real-Debrid"
