- 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
- Replace `scc_cstring_from_cstr(scc_cstring_as_cstr(...))` with `scc_cstring_copy()` in lexer to fix memory leaks
- Extract macro expansion logic into separate `expand_macro.c` file
- Remove `expand_stack` parameter from `scc_pp_expand_macro()` function
- Add new parsing functions for macro replacement lists and arguments
- Add string utility functions for whitespace trimming and string joining
- Update memory stream documentation for clarity
- 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
Updated type names from `core_*` to `scc_*` across lex_parser and stream modules to maintain naming consistency within the SCC codebase. This includes changes to function signatures and internal usage of types like `core_probe_stream_t`, `core_pos_t`, and `cstring_t` to their `scc_*` counterparts.
- Rename `cstring_push` to `cstring_append_ch` and `cstring_push_cstr` to `cstring_append_cstr` for consistent naming with new `cstring_append` function
- Update all callers in lexer and tests to use new function names
- Rename stream `destroy` method to `drop` for consistency with resource management conventions
- Fix potential overflow in string capacity calculation by adjusting growth logic
