/**
 * Smoke-test helper for extractor manifests: imports each manifest, runs it with a
 * minimal context, and prints mapped job counts + a sample row.
 *
 * Run from repo root (`run-smoke-extractors.mjs` applies repo tsconfig for `@shared/*`):
 *   npm run smoke:extractors
 *   npm run smoke:extractors -- arcdev,icims
 *   npm run smoke:extractors -- indeed    # alias → `jobspy` (same manifest)
 *
 * Keep `ALL_TARGETS` aligned with every shipped manifest under each
 * `extractors/<name>/` package (`manifest.ts` or `src/manifest.ts`).
 *
 * Loads repo-root `.env` so keyed extractors match orchestrator behavior (plain
 * `tsx` does not read `.env` automatically).
 *
 * Resolves `@shared/*` imports in extractor manifests via `scripts/smoke-resolve-shared.mjs`.
