feat: Mark MAE/MFE Analysis as complete in roadmap

Changes:
- Updated roadmap status from 'planned' to 'complete'
- Added checkmarks for implemented features:
  ✅ Position Manager tracks MFE/MAE every 2 seconds
  ✅ Database stores maxFavorableExcursion and maxAdverseExcursion
  ✅ Analytics dashboard displays avg MFE/MAE per indicator version
  ✅ Version comparison shows MFE/MAE trends
  ✅ Optimization API analyzes MFE vs TP1 rate
- Added future enhancement note for distribution charts

Evidence:
- Position Manager: lib/trading/position-manager.ts (lines 53-55, 140, 1127+)
- Database: Trade model with MFE/MAE fields
- Analytics: app/analytics/page.tsx (lines 77-78, 566-579, 654-655)
- Optimization API: app/api/optimization/analyze/route.ts

User Request: 'i think we already have this implemented?'
Confirmed: MAE/MFE tracking is fully operational
