feat(analysis): v3 re-analysis with 31 ECOS variables

Best model: CREDIT_SPREAD_LAG1 + USDKRW + HOUSING_PRICE (R²=0.646)
- 31 raw vars → 80+ features (DIFF/LAG1/PCT/spreads)
- 2267 valid combos searched (collinearity filtered)
- All Top 10 sign-consistent
- Zt sign corrected: Z+ = 호황 (Belkin convention)

refactor(macro): sign-consistent re-analysis, rate DIFF only

- Removed CORP_AA_LOGR (log of rate = problematic near zero)
- Rate variables restricted to DIFF only (no LOG/PCT/LOGR)
- Added economic sign consistency checks for all 45 features
- New optimal 3-var: CREDIT_SPREAD_LAG1, IPI_LAG1, EXPORT_DIFF
  - All coefficient signs economically consistent
  - R²=0.586 (trade-off: lower R² but correct economics)
- Added IPI + EXPORT to ECOS queries and fallback data
- Zt restricted to 2000-2025 in analysis (26 obs)
- Pipeline 8/8 validation pass

feat(macro): comprehensive variable exploration, R²=0.028→0.747

- New: data/macro_analysis.py (15 base × 6 transforms = 116 candidates)
  - Top correlations: CORP_AA_LOGR(r=-0.75), credit spread, term spread
  - Exhaustive 3-var search (1749 combos), best adj.R²=0.71
- Modified: data/macro_data.py
  - Added GOVT_3Y, CORP_AA, CORP_BBB ECOS queries + fallback data
  - New: compute_derived_features() for optimal 3 predictors
- Modified: main.py
  - Computes derived features + passes combined input to stepwise
  - Scenario paths now include derived features for prediction
- Selected 3 variables: CORP_AA_LOGR, CPI_GROWTH, CREDIT_SPREAD_LAG1
- All 8/8 validation tests pass (incl. R² now Pass)
