Module quantum 

High-performance quantum annealing primitives.

Accelerates the hot paths in the Python quantum_annealing bridge:

• Simulated annealing: Metropolis-Hastings with exponential schedule
• Ising energy: Vectorized energy evaluation
• Gauge transform: Batch gauge generation and application
• Problem decomposition: Greedy graph partitioning
