✨ feat(sidebar-batch-table): 批量操作表新增对象筛选与作用范围控制

- 批量操作表弹窗新增关键字筛选（忽略大小写包含匹配）
- 新增类型筛选（全部对象/仅表/仅视图）
- 新增勾选作用范围切换（当前筛选结果/全部对象）
- 全选、取消全选、反选逻辑按作用范围执行
- 筛选区域展示命中计数与无匹配空态提示
- refs #130

+### Linux 启动报错缺少 `libwebkit2gtk` / `libjavascriptcoregtk`
+
+GoNavi 的 Linux 二进制依赖系统 WebKitGTK 运行库。不同发行版默认版本不同：
+
+- Debian 13 / Ubuntu 24.04 及更新版本：通常为 WebKitGTK 4.1
+- Ubuntu 22.04 / Debian 12 等：通常为 WebKitGTK 4.0
+
+如果启动时报错（如 `libwebkit2gtk-4.0.so.37: cannot open shared object file`），请按系统安装对应依赖后重试：
+
+```bash
+# Debian 13 / Ubuntu 24.04+
+sudo apt-get update
+sudo apt-get install -y libgtk-3-0 libwebkit2gtk-4.1-0 libjavascriptcoregtk-4.1-0
+
+# Ubuntu 22.04 / Debian 12
+sudo apt-get update
+sudo apt-get install -y libgtk-3-0 libwebkit2gtk-4.0-37 libjavascriptcoregtk-4.0-18
+```
+
+如果你使用的是 Release 中带 `-WebKit41` 后缀的 Linux 产物，请优先在 Debian 13 / Ubuntu 24.04+ 上使用；普通 Linux 产物更适合 WebKitGTK 4.0 运行环境。
