Implement hybrid knowledge search using Cloudflare Vectorize + Workers AI embeddings (bge-base-en-v1.5, 768d) merged with existing D1 LIKE queries, with graceful degradation when Vectorize is unavailable. Add admin API endpoints for batch/single article indexing. Add 4 proactive notification cron jobs: server status changes, deposit confirmation/rejection alerts, pending payment reminders (1h+), and bank deposit matching notifications — all with DB-column-based deduplication.
