feat: rename core types to scc prefix 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.
