Save property

Save or update a hosted property in the registry. Requires authentication. For existing properties, creates a revision-tracked edit. For new properties, creates the property directly. Cannot edit authoritative properties managed via adagents.json.

This is an identity-only write surface: the stored document always carries authorized_agents: []. Sales authorization lives solely in the publisher's own origin adagents.json; the community registry cannot mint or carry it. Any authorized_agents sent in the request body is ignored.
