What this skill does

Extract durable ktx wiki knowledge from staged Sigma data model specs and workbook summaries. Load for WorkUnits with unitKey sigma-data-models or sigma-workbooks. Sigma ingest turns staged data model specs and workbook summaries into durable ktx wiki knowledge. The deterministic project() step has already written semantic-layer YAML for all warehouse-table data model elements before this skill runs — do not re-write those SL sources.
