[Feature] Add-ons Bundles (URL parameter distribution)

[Jarvis2001]

New

• Users/guests can receive pre-configured add-on collections via URL parameter
• Syntax: ?addonsCollection=https://example.com/collection.json
• Automatically installs installable add-ons; configure-only ones are skipped (expected behaviour since API Keys)
• Includes error handling, deduplication, and user notifications
• Backwards compatible, no breaking changes

Testing

• Local Testing
