09f4ac8de0 feat(lex_parser, pprocessor): replace consume with next and remove stream resets
- 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

07f5d9331b feat(lexer, preprocessor): replace cstring conversion with copy and refactor macro expansion
- 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

07a76d82f4 feat(lex_parser, pprocessor): rename identifier header check and add macro system
- 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

d88fa3b8d3 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.

186602a301 feat(core): rename string and stream functions for clarity
- 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

871d031ceb feat(lex_parser): 初始化词法解析器模块
新增词法解析器库 `smcc_lex_parser`,包含基础的词法规则解析功能:
- 支持字符、字符串、数字、标识符的解析
- 支持跳过注释、空白符、行尾等辅助函数
- 提供对应的单元测试用例,覆盖各类合法与非法输入情况

该模块依赖 `libcore`,并被 `smcc_lex` 模块引用以支持更上层的词法分析逻辑。

a3322f0d4c feat(runtime): 添加字符串和内存操作工具函数
- 在 `core_mem.h` 中新增 `smcc_strhash32`、`smcc_strlen` 和 `smcc_strcmp` 函数,
  提供 C 字符串的哈希、长度获取和比较功能
- 完善 `core_str.h` 中 `cstring_t` 结构体及相关操作函数的注释说明
- 更新 `core_str.h` 头文件保护宏命名,增强模块标识一致性
- 修改 `core_vec.h` 文件头部保护宏名称以匹配实际文件名

另外,在 lexer 测试运行代码中引入日志相关头文件并调整日志级别设置逻辑。

f29fd92fdf feat(core): 添加字符串长度计算函数并优化数据结构定义
- 在 `core_mem.h` 中新增 `smcc_strlen` 函数,用于计算字符串长度
- 调整 `VEC` 宏定义参数,移除冗余的 name 参数,增强结构体声明一致性
- 修改 `cstring_from_cstr` 返回值字段顺序,保持代码风格统一
- 在 `libcore.h` 中增加日志相关宏定义的保护判断,防止重复定义冲突

47b56d52f6 feat(core): 重构词法分析器流接口并迁移至 core 库
将 lexer_stream 抽象为 core_stream,统一运行时核心组件的输入流模型。
移除了旧的 `lexer_stream.h` 定义,并将其功能完整迁移至 `core_stream.h` 中。
更新了内存流实现以适配新的 core_stream 接口,并修复部分资源释放问题。
同时调整日志模块包含方式,增强模块间解耦能力。

此变更影响词法分析器对输入流的操作方式,所有涉及 stream 的类型与函数均已替换为 core 前缀版本。
测试用例同步更新并验证通过。
