New: strategies/persistence.py
Tables: strategies_snap, trade_log, equity_history, fill_tracker
Auto-creates on first use, batches inserts per tick
Fix: seen_fills loads from PG (not 2000 API fills)
Before: every restart loaded all 2000 fills from API into
seen_fills, blocking new fills with matching TIDs for ~20min
After: only loads last 100 from API + full history from PG.
New fills saved to PG immediately - survives restarts.
Live node integration:
- write_metrics() → save_strategies() every tick
- On fill → save_trade() to trade_log
- On fill → TID saved to fill_tracker for cross-restart dedup
