- Rename `scc_lex_parse_is_identifier_header` to `scc_lex_parse_is_identifier_prefix` for clarity and add a TODO comment - Update lexer to use the renamed function for consistency - Fix package and dependency names in `cbuild.toml` (`smcc_pprocesser` → `scc_pprocesser`, `smcc_lex_parser` → `lex_parser`) - Introduce new macro system with header file `pp_macro.h` defining macro types, structures, and management functions - Refactor preprocessor initialization and cleanup in `pprocessor.c` to use new macro table and stream handling - Replace legacy `hashmap` with `scc_pp_macro_table_t` for macro storage - Improve error handling and resource management in preprocessor lifecycle
