- 将IR构建器初始化函数修改为接受cprog参数 - 添加scc_ast2ir_ctx_drop函数用于资源清理 - 更新类型标识符命名规范，从大写改为小写形式 - 替换scc_ir_ctx_get_*函数调用为scc_ir_module_get_*函数 - 移除对ir_builtin.h的依赖，改用ir_builder.h中的构建器函数 - 为整数常量创建添加专门的构建器辅助函数 fix(ir): 重构IR上下文和模块管理结构 - 将原有的scc_ir_cprog_ctx_t拆分为scc_ir_module_t和scc_ir_ctx_t - 添加scc_ir_module_t结构用于统一管理IR对象存储 - 更新IR类型枚举名称格式，从SCC_IR_TYPE_XXX改为SCC_IR_TYPE_xxx - 添加整数、无符号整数和浮点数常量联合体定义 - 移除ir_base.h和ir_builtin.h头文件，整合到scc_ir.h中 feat(ir_builder): 添加类型构建器函数和常量创建功能 - 为各种基础类型添加scc_ir_builder_type_*内联函数 - 实现scc_ir_builder_const_int函数用于创建整数常量 - 修改构建器初始化函数签名以接受cprog参数 - 更新构建器内部结构，使用指向cprog的指针而非嵌入式结构
