feat: Archive old indicator versions, focus on v8 production system

Version Management:
- v8 Money Line: PRODUCTION (8 trades, 57.1% WR, +$262.70, quality ≥95 = 100% wins)
- v5/v6/v7: ARCHIVED (historical baseline for future v9 comparison)

API Changes (app/api/analytics/version-comparison/route.ts):
- Added 'archived' flag to version stats
- Added 'production' field pointing to v8
- Updated sort order: v8 first, then archived versions
- Enhanced descriptions with PRODUCTION/ARCHIVED labels

UI Changes (app/analytics/page.tsx):
- v8 highlighted with blue gradient + 🚀 PRODUCTION badge
- Archived versions greyed out (60% opacity) + ARCHIVED badge
- Updated header: 'Indicator Versions (v8 Production)'
- Data collection notice: v8 shows 8/50 trades progress
- Kept comparison infrastructure for future v9 development

Documentation (.github/copilot-instructions.md):
- Updated Indicator Version Tracking section
- Documented perfect quality separation (≥95 = 100% wins)
- Clarified v8 production status, archived versions purpose
- Analytics UI behavior documented

Purpose: Keep comparison infrastructure for statistical validation
and future v9 testing while focusing user attention on v8 results.

-- **v6:** HalfTrend + BarColor strategy (Nov 12-18) - baseline performance, prone to flip-flops in choppy markets

+- **v8:** Money Line Sticky Trend (Nov 18+) - **PRODUCTION SYSTEM**
   - Flip threshold: 0.6% (price must breach line by 0.6% before signal change)
   - Momentum confirmation: Tracks consecutive bars beyond threshold (anti-whipsaw)
-  - Confirm bars: 0 (user-tuned, immediate signals with threshold protection)
-  - Entry buffer: 0.2 ATR (filters wick flips)
-  - ADX minimum: 18 (up from 14, stronger trend requirement)
-  - Stickier multipliers: Minutes 3.8x, Hours 3.5x, Daily 3.2x, Weekly 3.0x
-  - ATR-based adaptation: Works on all timeframes (5min to daily)
-  - Visual backtest: Near-perfect accuracy, significantly fewer false signals than v6/v7
