reverse_prefix_simple

Simple prefix reversal without coordinate tracking.

Implements algorithms for analyzing Cayley graphs of permutation groups,
with a focus on the TopSpin puzzle and similar permutation-based combinatorial
puzzles. Provides methods for cycle detection, state space exploration,
bidirectional BFS pathfinding, and finding optimal operation sequences
in permutation groups generated by shift and reverse operations.
Includes C++ implementations of core operations via 'Rcpp' for performance.
Optional GPU acceleration via 'ggmlR' Vulkan backend for batch distance
calculations and parallel state transformations.
