Code Review

This pull request introduces the GLOBAL_ROUTE_USE_CUGR configuration variable to allow using CUGR as the global routing solver instead of FastRoute. It updates the global routing script, documentation, and schema files. Feedback was provided regarding the need to also pass the CUGR flag to incremental global routing calls to ensure consistent solver usage throughout the routing process.
