jgrusewski 1fae917c22 perf(cuda): H100 kernel optimizations — nvcc pipeline, kernel fusion, GPU-only training ...

- Migrate from NVRTC JIT to cached nvcc -O3 for all CUDA kernels
- Fuse guard kernels, increase prefetch chunk, eliminate per-step GPU alloc
- H100-specific: fused Adam, warp reductions, shmem tiling, PPO occupancy
- Vectorize gather_states with __ldg() and 4x unroll
- sincosf() Box-Muller + paired Gaussian generation in noisy nets
- Shared-memory tiled branching DQN forward pass for sm_<90
- GPU-resident training guard kernel replacing Candle tensor ops
- Eliminate all to_vec1/to_vec2 CPU roundtrips, DtoD weight copy
- GPU PER mandatory everywhere — kill CPU replay path on CUDA
- Full GPU action masking — eliminate CPU fallback path
- Fix cuBLAS handle sharing via OnceLock (root cause of 49 cascade failures)
- Fix ILLEGAL_ADDRESS: scratch1_dist buffer overflow, stack sizing, curand determinism
- Fix CudaStream lifetime: bind before .context() to extend lifetime
- Keep raw cudarc buffers alive across epochs
- Add gpu-hotpath-guard.sh (37 patterns) and ptx-cache-invalidate.sh
