FlowMint Workflows v0.9.0

Added

• pre_upsert_records maps featured_image_url. A feed that supplies
  photo URLs can map them per record; Post Runtime (0.10.0+) sideloads each
  URL into the media library once — a re-run with the same URL reuses the
  attachment — and sets it as the record's featured image. A URL that
  cannot be fetched or is not an image is a per-record warning, not a
  failure, so the record is still written. Closes the "image sideloading for
  ingest" follow-up in the external-ingest pattern.
