Mantle - Auto fix old deprecated SDK

We analyse your GitHub repository, identify every SDK/library you use, and detect outdated/deprecated dependencies. We understand how those dependencies are actually used in your codebase and tell you: * what changed in the new version * whether your existing code will break * exactly what code changes you need to make * which parts of your codebase need updating Then we create actionable github issue explaining all which your agent can then implement actually.
