Worked on the nndeploy/nndeploy repository to enhance code stability by addressing a critical naming inconsistency in global function maps used for codec node creation and registration. Applied C++ and Markdown skills to refactor the codebase, renaming the global maps to GlobalCreateDecodeNodeFuncMap and GlobalCreateEncodeNodeFuncMap and updating all related shared pointer references. This correction eliminated potential runtime errors and improved the reliability of the decoding and encoding pipeline without introducing new features. The work focused on typo correction and code hygiene, reducing future regression risk and supporting safer deployment pipelines for ongoing and future enhancements within the project.
