When processing high-resolution textures (e.g., 2048x2048) on complex meshes with millions of faces, a single BVH unsigned_distance query can cause GPU watchdog timeout. This adds a _batched_unsigned_distance() helper that splits queries into 100K-element batches (matching the rasterization chunk size), preventing kernel timeout while maintaining identical results. Fixes texture baking hangs at "Sampling attributes" step on large meshes. Related: PozzettiAndrea/ComfyUI-TRELLIS2#19
