/**
 * Machine-readable per-recipe progress stream for `recipe push`.
 *
 * Orchestrators run the push with `--json`, which suppresses the
 * human per-recipe logging — so a large push is silent for minutes.
 * With `SITECOREAI_PROGRESS_STREAM=1`, the push writes one compact
 * NDJSON line to STDERR as each recipe finishes executing:
 *
 *   {"scaiProgress":1,"recipe":"page-home@1","index":12,"total":237,
 *    "status":"succeeded","summary":{"create":3,"update":8,"skip":4,"error":0}}
 *
 * stderr so the `--json` stdout envelope stays parseable. Consumers
 * (the showcase orchestrator's task runner) tail the stream and turn
 * each line into a live progress event. Off by default — plain CLI
 * runs and older orchestrators are unaffected.
