Add LibraryIQ plugin

[wadforth]

Adds LibraryIQ as a PluginDatabase submodule.

LibraryIQ enhances the Steam Library sidebar with Steam review percentage badges, rating-based sorting/filtering, badge customisation, and a quick filter control.

Plugin repository:
https://github.com/wadforth/LibraryIQ

Tested:

• bun run build
• Steam launches with the plugin installed
• Sidebar review badges render
• Settings panel opens
• Rating source/display options work
• Quick filter appears in the Library

Notes:

• LibraryIQ modifies the Steam Library UI through Millennium/React runtime patching.
• Sorting/filtering is designed to work with Steam’s virtualised Library list.

Plugin uses custom AI generated UI components on the Sidebar navigation. @steambrew/client had many builtin components, and you can refer to the PluginTemplate

All custom UI elements have been replaced with the native components. Please review.
