Distributed Image List Start no longer has reference_image, text,
strength, seed or per-slot mode dropdowns. It now takes images, mask and
up to 10 generic value_N inputs (IMAGE, MASK, STRING, INT, FLOAT,
BOOLEAN) that grow via native V3 Autogrow, each with a matching output.
- One value is shared by every image; one per image pairs in order; any
other count fails before dispatch. Only images is split into frames.
- Outputs are declared up front (image, mask, item_index, context,
value_1..value_10). web/imageListStart.js hides unused value outputs,
mirrors input types, and follows Autogrow compaction so downstream
links keep their value.
- Image-list protocol bumped to v2; older workers fail preflight.
Breaking: saved workflows using the old Start inputs must recreate Start.
