How to do batch inference?

Reviewed for v0.5.0: multiple points/rectangles for one image are supported, but true multi-image batch inference is not yet a stable contract—SAM1 embedded preprocessing is rank-3 per image and the split families have different batching constraints. Leaving this open as an enhancement. A future implementation should batch only compatible same-size encoder inputs while preserving per-image prompt lists and original sizes.
