P1-①: error_init/add 从 malloc/realloc/strdup 改为 arena_alloc/arena_strdup P1-②: impl 方法中 Self 类型在 sema 解析为实际结构体名 P1-③: trait 方法 fallback 增加前缀校验(strncmp)，method_name 统一更新 P1-④: codegen args[16] 增加溢出检查，移除 parser 未使用的 mods/uses 数组 新增: 36_self_type.l 集成测试（Self 类型 + trait 方法） Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
