As a registry API consumer, I want to include soft-deleted entries in query results, so that I can support incremental sync and moderation workflows

The upstream API spec added a query parameter to handle soft deleted entries. Soft delete means records are never physically removed from the database. Instead, a status field is set to deleted, which hides them from default API listings.

Details:

• Passing include_deleted=true as a query parameter reveals them again
• Since the data is preserved, deletion is reversible so setting the status back to active restores the record
• Intended for incremental sync, where downstream consumers need to learn about deletions, and for moderation/takedown workflows where metadata should remain accessible even after removal from public listings
• There is no defined retention policy.
