boot() method, after FLEX has registered its services. Supply the built local files that your package ships.
Register catalog recommendations through FlexCatalog::registerPlugin() in the
same provider-boot phase. Both component collection and catalog registration freeze
after providers have booted. A request or queue job cannot add recommendations to
the process registry. Catalog services remain lazy on pages that do not use them.
Use a unique vendor prefix. Extensions cannot replace built-in aliases, shared JavaScript chunks, global styles, registered asset identities or the official FLEX badge.
register($definition, styles: [...], entryPath: ...) uses the same validation.
