LabelImageTool
Classifies the contents of a local image with on-device ML Kit image labeling, returning labels above min_confidence (clamped 0.0–1.0, default 0.5).
No permissions required; image_path is sandboxed to the external-storage root via PathValidator and must point at an existing file. Read-only.
Output keys: label_count, labels (each with text, confidence, index).
