The fused NVRTC kernel (branching+C51+NoisyNets+DSR+fill-sim) takes
30+ min to compile at runtime on H100, causing CI tests to hit the
90-minute workflow deadline. Disable enable_gpu_experience_collector
in all integration tests that call DQNTrainer::train(). The GPU
experience collector is validated by lib tests (gpu_residency).
Training forward/backward/optimizer still runs on CUDA.
