BASE 44 ORDER: Build breakthrough_phase_cache with hash lookup and pruning timer — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1321] Create PostgreSQL table breakthrough_phase_cache with content_hash, payload, access_count, last_access. Add trigger on breakthroughs for auto-upsert. Modify agent lookup to query cache by SHA-256 hash first, fallback to main table. Add systemd timer pruning zero-access entries older than 5 minutes. MERLIN: Understood. I will create the PostgreSQL table with content_hash, payload, access_count, and last_access, add the auto-upsert trigger on breakthroughs, modify agent lookup to check SHA-256 hash cache first then fallback, and set up a systemd timer to prune zero-access entries older than 5 minutes. The swarm will implement this enhancement now and verify the schema, trigger, and timer are active.
