Move personas off the mobile client into ImageApi as first-class records, and scope entity_facts by persona so each one builds its own voice over a shared entity graph. The new include_all_memories flag lets a persona opt back into the full hive-mind pool for human browsing of /knowledge/*; agentic generation always stays in-voice.
