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
