Summary: Use BoundsCheckMode.V2 for Triton TBE standalone index validation. This preserves the existing warning and offset-repair behavior while reducing validation overhead before Triton forward. Reviewed By: axeisghost, TroyGarden Differential Revision: D114279989
Summary: Validate and repair indices inside supported unweighted, non-VBE Triton forward kernels. Unsupported configurations retain the CUDA v2 fallback, while fused checked loads preserve warning accumulation without a separate full-index pass.

Summary:
Convert long bags over small tables into per-bag row histograms followed by a tensor-core dot. Generic row, dimension, and bag-size predicates select the route, and checked loads preserve fused bounds behavior.
