Adds ETL pipeline for state-level individual income tax collections using Census Bureau's Annual Survey of State Government Tax Collections (STC). - New ETL script: etl_state_income_tax.py with FY2023 data for all 50 states + DC - Uses stratum_group_id 7 for state income tax strata - Includes proper handling for states without income tax (AK, FL, NV, SD, TX, WA, WY, NH, TN) - Ohio value confirmed at $9.52B matching external sources - Total collections across all states: ~$531B This addresses the calibration gap where PolicyEngine was overestimating state income tax (e.g., $24B for Ohio vs actual $10B) due to missing calibration targets.
