Summary

Reworks the Store into a marketplace: Discover rows and filters, tags, a polished detail page with an older-version selector, compact reviews, recommendations and a footer. Adds an optional AI self-declaration to plugin and icon pack manifests, shown in the Store.

Testing

Build with warnings as errors, host (9324), SDK, CLI, localization, desktop UI (4394) and web client pass. Verified in a disposable host at several widths, including a real install and uninstall; a real downgrade was not testable on macOS and is covered by host tests.

Plugin SDK / API compatibility

• No public, non-obsolete SDK or plugin protocol contract was removed or changed
• Contracts were only extended additively (new members with defaults, new optional fields, new message types)
• A plugin compiled against the previous SDK still loads and behaves identically (source and binary compatible)

Notes

Host API: the version in an install request is now binding, and retry answers not_found for failures a retry cannot fix. Tags, AI declarations and categories appear once the Platform publishes them to the registry.
