- Replace `scc_probe_stream_consume` with `scc_probe_stream_next` for consistent stream advancement
- Remove redundant `scc_probe_stream_reset` calls before peeking, as `next` and `peek` handle state
- Update `scc_cstring_new` to `scc_cstring_create` and `scc_pos_init` to `scc_pos_create` for naming consistency
- Change `scc_pp_macro_get` parameter to `const scc_cstring_t*` for better const-correctness
- Improves code clarity and maintains proper stream position tracking
- Change `scc_macro_table_t` to `scc_pp_macro_table_t` for consistency
- Rename `scc_pp_macro_create` to `scc_pp_macro_new` for naming convention
- Remove unused `scc_pp_compress_whitespace` function
- Update macro table function names: `scc_pp_find_macro` → `scc_pp_macro_table_get`, `scc_pp_remove_macro` → `scc_pp_macro_table_remove`
- Add new `scc_pp_macro_table_set` function for setting macros
- Update all function signatures to use new type name
- Remove commented-out whitespace compression code from implementation
- 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
