* **Documentation** * Added new C coding style guide detailing naming conventions for files, directories, macros, constants, variables, functions, and type definitions with illustrative examples. * Updated C++ coding style documentation with clarifications on C naming conventions and header directory organization patterns. * **Refactor** * Updated header include paths throughout the codebase to use lowercase naming conventions consistently.
