CUDA Kernel-Lens Performance Extension

Gaurav built a CUDA Kernel-Lens extension that works with VSCode using Jev. It surfaces performance signals while writing kernels, before compiling, profiling, or consulting a coding agent, and highlights segments with strided memory access or repeated loads of reusable operands from global memory.

Took JEV for a spin this weekend and built (read vibed) this CUDA Kernel-Lens extension (works with VSCode). The idea is simple - get performance signals right where you are writing the kernel - before compiling, profiling or asking a coding agent to chime in. It highlights segments where the code is plagued with strided memory access, repeatedly loading reusable operands from the global memory, b
