This release improves correctness and developer confidence in std::format and related APIs, with a clear commit history and enhanced test coverage.

January 2025: Implemented BTOWC declaration addition to wchar.yaml to enable btowc in wchar.h and consolidated header declarations to remove duplicate includes in generated C library headers.
