fix(log): merge extra callStacks into structured field, add isLogPkgFile for module-path compatibility

- Error() now merges callStacks from extra into entry.CallStacks
- New isLogPkgFile helper handles both local and module proxy paths

 # Changelog
 
+## [1.5.7] - 2026-06-20
+- **调用栈容错增强**:
+  - `Error` 方法现在支持通过 `extra` 参数传入 `callStacks` 字段，自动合并到结构化的 `CallStacks` 字段中，避免外部调用栈信息丢失。
+- **模块路径兼容**:
+  - 新增 `isLogPkgFile` 辅助函数，统一处理本地路径 (`.../log/file.go`) 和 Go module 版本路径 (`.../log@v1.5.6/file.go`) 的文件匹配，确保在 module proxy 场景下调用栈过滤同样精准。
+
+## [1.5.6] - 2026-06-20
+- **基础设施对齐**: 内部依赖统一升级至 v1.5.x 语义版本。
+
 ## [1.5.5] - 2026-06-05
 - **规范化: Warning 日志行为对齐**:
   - ** Convention 对齐**: 移除了 `Warning` 级别日志自动附带堆栈信息（`CallStacks`）的逻辑。
