Compute Disparate Impact Metrics

Computes three fair lending disparate impact metrics from aggregate lending counts: 4/5ths (80%) rule (adverse_impact_ratio) per EEOC 29 CFR §1607.4(D), z-statistic for statistical significance of the approval-rate difference, and standardised mean difference (Cohen's d). Inputs are aggregate counts only; no individual applicant records, names, demographic identifiers, or scores. ZERO PII BY CONSTRUCTION. EEOC Uniform Guidelines on Employee Selection Procedures (29 CFR §1607), HMDA/Reg C.
