Pull Request resolved: #21160 Ports `pow.Tensor_Tensor` with NumPy broadcasting, mirroring the sibling `mul` op + Vulkan `binary_op_buffer` (per-tensor `TensorMeta` uniforms; size-1 input dims clamped and the flat output index relinearized; equal-shape fast path). Key changes: - `runtime/ops/pow/{BinaryOp.cpp, binary_pow.wgsl}` (+ generated `_wgsl.h`) — `pow_impl` (args `[in1, in2, out]`); broadcast `TensorMeta` path + dual-operand resize hook; fail-loud int guard (fp32-only backend). Note: WGSL `pow(x, y)` is undefined for `x < 0`, exact parity with the Vulkan GLSL `pow`.
