TextOnlyImageDropNotice typedef

TextOnlyImageDropNotice = void Function(int droppedCount)

Host-set hook for the text-only strip (downgradeUnsupportedImages): reports how many image blocks the model's declared modalities dropped, so the run shows a VISIBLE notice instead of silence (issue #638). Null (the default) keeps the strip silent.

Implementation

typedef TextOnlyImageDropNotice = void Function(int droppedCount);
