jgrusewski e04edc0a84 feat: 9-exposure CUDA kernels — formula-based fraction, generalized flat_idx ...

- common_device_functions.cuh: DQN_NUM_ACTIONS 5→9, TOTAL_ACTIONS 45→81
- experience_kernels.cu: exposure_idx_to_fraction() formula (-1+idx*0.25)
- experience_kernels.cu: action_to_exposure() same formula
- backtest_env_kernel.cu: switch→formula for 9-level mapping
- All Q-gap flat_idx: hardcoded 2 → b0_size/2 (generalized)
- c51_loss_kernel.cu: MAX_BRANCH_SIZE 5→9, BRANCH_0_SIZE 5→9
