fix: resolve all remaining load_cubin(ptx) references + dead nvrtc stubs

Browse Source 
Replace all 20 dangling `ptx` variable references with correct cubin
static names after nvrtc removal sed. Fix ml-dqn dead code stubs
(residual.rs, rmsnorm.rs, noisy_layers.rs, gpu_replay_buffer.rs).
Clean up unused `let ptx` variables.

Zero compilation errors across full workspace.
