jgrusewski 1a93b71c69 feat(v8): wire 5 dead CUDA kernels + config fixes ...

Kernels now wired with Rust load + launch methods:
- popart_normalize_kernel: running mean/var + in-place normalization
- exposure_pretrain_step: supervised direction pre-training with backward GEMM
- td_lambda_kernel: exponentially-weighted lambda-returns
- compute_difficulty_scores: per-bar curriculum difficulty
- hindsight_relabel_kernel: optimal exit relabeling

Config fixes:
- batch_size hyperopt range: [64, 512] → [512, 8192] (H100 capacity)
- micro_reward_scale: 0.001 → 0.01 (10x stronger bootstrap)
- micro_reward hyperopt range: [0, 0.005] → [0, 0.05]

900 tests pass, 0 regressions.
