This PR extends the C API to add support for saving the problem to a file, adding initial primal and dual solutions for LP, and initial solutions for MIP. This functionality exists in the underlying C++ layer, and is a feature of most LP/MIP solver APIs available. Kept as a draft for now, as it is intended as a proposal to iterate on. closes #719 closes #720 ## Summary by CodeRabbit * **New Features** * Write optimization problems to MPS files. * Set initial primal and dual solutions for LP solves and specify initial MIP starts. * Check semantic equivalence between optimization problems. * **Enhancements** * Improved MPS writer: explicit handling of orphan variables and refined bounds/objective emissions. * **Tests** * Added MPS write/read roundtrip tests to validate I/O and equivalence. <sub>✏️ Tip: You can customize this high-level summary in your review settings.</sub> Authors: - Alice Boucher (https://github.com/aliceb-nv) - James Lamb (https://github.com/jameslamb) Approvers: - Ramakrishnap (https://github.com/rgsl888prabhu) - Rajesh Gandham (https://github.com/rg20) URL: #721
