create-persistence-adapter

Scaffold or update a complete JPA persistence adapter (outbound adapter) — entity, JPA repository, mapper, and adapter class — for a domain aggregate. Use when the user asks to "create a persistence adapter", "generate a JPA adapter", "scaffold the persistence layer", or "create an outbound db adapter". Accepts a repository port file or domain entity; generates all four files at once; updates existing files by adding missing methods or fields.
