- Position Manager now detects TP1/TP2 fills by monitoring position size reductions instead of entry price mismatches
- When position size reduces by ~75%, marks TP1 as filled and updates currentSize
- When position size reduces by ~95%, marks TP2 as filled and activates trailing stop for 5% runner
- Entry price mismatch check now skipped after TP fills (Drift shows weighted average entry price after partial closes)
- Fixes bug where runners were incorrectly closed after TP1/TP2 fired on-chain
- Adds grace period for new trades (<30s) to avoid false positives during blockchain propagation delays
- This unblocks Phase 1 data collection for signal quality optimization (need 10+ trades with MAE/MFE data)
