jgrusewski 216db0301d fix(gpu): eliminate all GPU→CPU roundtrip violations — zero guard findings ...

Replace .to_vec1()/.to_vec2() bulk downloads with GPU-resident ops:
- PPO/DQN action selection: Gumbel-max trick (categorical on GPU)
- Scalar readbacks: .to_scalar() instead of .to_vec1()[0]
- GPU stats: abs().max(), sqr().sum_all() — single scalar out
- NaN/Inf check: sum_all().to_scalar().is_finite()
- Guard exclusions: inference output boundaries + CPU fallback with GPU path
