Add cmm_ortools_solver.py with a CBC-based Mixed-Integer Program (continuous allocation flow, binary supplier activation, unmet demand slack) that handles demand, capacity, max-share, and linearized composition constraints. The existing greedy heuristic becomes a fallback when OR-Tools is not installed. Extract _build_output() so both paths produce an identical output schema, and add _try_ortools() wrapper with lazy import. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
