math_opt: xpress fixup

2026-09-11

math_opt: cleanup

Implement callback support for Xpress We implement full support for the callback in Xpress. The Xpress implementation supports all events and all features of the ortools callbacks. We also added a "solution source" attribute to the callback data in case of the MIP_SOLUTION event because we think this can be useful. In general the Xpress callback is much richer than what the ortools callback offers but we did not want to add too many things that could be Xpress-specific and might not be available with other solvers.

routing: removing the Routing prefix to some of the main classes. Now that the routing namespace has been created, we don't need it anymore. Added aliases to maintain compatibility in C++. List of renamed classes: - routing::RoutingModel -> routing::Model - routing::RoutingDimension -> routing::Dimension - routing::RoutingSearchStats -> routing::SearchStats - routing::RoutingModelVisitor -> routing::ModelVisitor - routing::RoutingLinearSolverWrapper -> routing::LinearSolverWrapper - routing::RoutingGlopWrapper -> routing::GlopWrapper - routing::RoutingCPSatWrapper -> routing::CPSatWrapper - routing::RoutingSolution -> routing::Solution routing: disable compatibility `using` when calling swig
