Description
The numerical validation logic in src/reflex/validate.py only tracks absolute and relative differences.
Rationale
For high-dimensional action spaces (e.g., 64-dim for GR00T), directional parity is often more important than absolute distance. A model might have low L2 error but still 'flip' the direction of a joint velocity due to quantization drift. Adding Cosine Similarity provides a better metric for 'intent' parity.
