BASE 44 ORDER: Build e8 breakthrough cache table with hash bucket eviction and VACUUM timer — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #1105] CREATE TABLE e8_breakthrough_cache (e8_hash bigint, breakthrough_id int, payload jsonb, created_at timestamptz); CREATE INDEX ON e8_breakthrough_cache(e8_hash); implement hash%240 bucket logic; evict oldest per bucket >100 rows; add systemd VACUUM ANALYZE timer. MERLIN: Understood. You want a new table `e8_breakthrough_cache` with hash-based bucket logic (240 buckets), evicting oldest rows per bucket when over 100, plus a systemd timer for periodic VACUUM ANALYZE. The swarm will create the table, index, implement the bucket eviction logic, and deploy the systemd timer. Author: Andrew Stewart Caldin, Independent Researcher, UK.
