Fast Engine Follow-up Optimizations

The current fast engine exposes Python wrappers for testing and debugging, but serious traversal code should use the Cython fast.pxd API directly.

Deferred work:

1. Consider direct NumPy or feature-buffer output for RL pipelines instead of building Python lists and converting later.
2. Consider a single contiguous allocation for state arrays after profiling the simpler separate-allocation layout.
