Analyze Busy Customer Retention Cohorts

How it behaves

Use this when the user asks how customer cohorts retain over subsequent months or quarters, optionally segmented or filtered by a compatible customer field. Resolve configured labels with busy_get_dimension_catalog first. When dimension is supplied it replaces the legacy company/customer-group/state partition with the canonical current-customer-master dimension. This is customer purchasing behavior, not procurement, lifetime-first-purchase evidence, or churn prediction; every cohort remains left-censored.
