docs: add C and C++ language support to documentation

- Update README.md with C and C++ language support
- Add C and C++ to supported languages table
- Document C extraction features (functions, structs, macros, etc.)
- Document C++ extraction features (classes, templates, namespaces)
- Update language filtering examples and config files
- Remove C++ from planned support (now implemented)
