jgrusewski 57a91567b4 fix(ci): PTX cache invalidation includes build.rs + all kernel dirs ...

The script only hashed .cu/.cuh in crates/ml/. Missed:
- build.rs changes (removing --use_fast_math → stale cubins cached)
- crates/ml-dqn/src/*.cu (replay buffer, seg tree kernels)
- crates/ml-core/src/cuda_autograd/*.cu
- crates/ml-ppo/src/cuda_nn/*.cu

Now hashes ALL kernel sources + ALL build.rs files. Any change to
nvcc flags or kernel source invalidates the entire PTX cache.
