feat(simulation): add Economic Conditions for regime tagging and evaluation - Issue #35 (53 tests)
Implements comprehensive economic and market regime analysis: - MarketRegime enum (BULL, MODERATE_BULL, SIDEWAYS, MODERATE_BEAR, BEAR) - VolatilityRegime enum (LOW, NORMAL, ELEVATED, HIGH) - RegimeDetector class for market/volatility regime detection - RegimeEvaluator for strategy performance by regime Features: - Statistical regime detection from return series - Trend strength and confidence assessment - Rolling window regime tagging - Performance breakdown by market regime - Performance breakdown by volatility regime - Regime transition detection and tracking - Regime-specific strategy recommendations - Overall regime score and adaptability metrics - Comprehensive report generation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
