/**
 * `harn models lora promote` renderer.
 *
 * Rust reads manifest/eval receipt files and builds the promotion matrix
 * receipt. This Harn source owns human presentation and JSON passthrough.
 *
 * Inputs:
 *   HARN_MODELS_LORA_PROMOTE_PAYLOAD_JSON   - compact report JSON.
 *   HARN_MODELS_LORA_PROMOTE_PAYLOAD_PRETTY - pretty report JSON.
 *   HARN_OUTPUT_JSON                        - "1" for JSON, else human text.
