Registered Products now covers the full Interplay catalogue and can install missing plugins.
- Central product catalogue: Interplay SEO, Interplay Reports, GF Jobber Sync, and the Intro Block Validator and Normalizer are registered by default alongside Intro and Interplay Services itself
- Missing plugins appear as 'Not installed' with a one-click Install button (authenticated GitHub release download, same pipeline as updates)
- Not-installed plugins are excluded from WordPress update checks
- Product plugins can still self-register/override via interplay_services_registry_loaded
