…n scalar DecomposeFloorDivide read .meta from both operands, so an integer floor_divide by a Python scalar (YOLO26's `index // nc`) crashed export with "'int' object has no attribute 'meta'". Trace the scalar as a 0-dim tensor and remap it back, and cast the result to the node's own dtype.

…n scalar DecomposeFloorDivide read .meta from both operands, so an integer floor_divide by a Python scalar (YOLO26's `index // nc`) crashed export with "'int' object has no attribute 'meta'". Trace the scalar as a 0-dim tensor and remap it back, and cast the result to the node's own dtype. Backport of pytorch/executorch#24034. 1.4.1 has no rework pass tests, so the subtest is an end-to-end lowering test in test_passes.py here.

Summary
DecomposeFloorDividereads.metafrom both operands, so an integerfloor_divideby a Python scalar crashes export with'int' object has no attribute 'meta'. YOLO26's detection head hits this (index // nc). The scalar is now traced as a 0-dim tensor and remapped back.Test plan
