- 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 header guard from `__SMCC_LEX_PARSER_H__` to `__SCC_LEX_PARSER_H__`
- Prefix all lexer functions with `scc_` (e.g., `lex_parse_char` → `scc_lex_parse_char`)
- Add new helper function `scc_lex_parse_is_identifier_header`
- Update references in source and test files to use new function names
- Replace `core_stream_eof` with `scc_stream_eof` for consistency
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.
