✨ feat(TableOverview): 新增表平铺视图概览功能

- 新建 TableOverview 组件：卡片网格展示表名、注释、行数、数据大小、引擎
- 数据获取：通过 DBQuery 发 SHOW TABLE STATUS 等 SQL 适配多数据库方言
- 交互功能：搜索过滤、按名称/行数/大小排序、双击打开DataGrid、Tooltip悬浮全名
- 右键菜单：与 Sidebar 完全一致（新建查询/设计表/复制结构/备份/重命名/删除/导出）
- 入口集成：双击侧边栏"表(N)"分组节点打开概览Tab，注册table-overview类型
- UI细节：统计指标固定列宽对齐，卡片hover高亮边框

+# Contributing Guide
+
+Thank you for contributing to this project.
+
+This repository follows a release-first workflow: `main` is the default public branch, while releases are prepared through `release/*` branches.
+
+---
+
+## Branch Model
+
+- `main`: stable release branch and default branch
+- `dev`: day-to-day integration branch for maintainers
+- `release/*`: release preparation branches for maintainers
+- Recommended branch names for external contributors:
+  - `fix/*`: bug fixes
+  - `feature/*`: new features or enhancements
+
+Maintainer release flow:
+
+```text
+feature/* / fix/* -> dev -> release/* -> main -> tag(vX.Y.Z)
+```
+
+---
+
+## How External Contributors Should Open Pull Requests
+
+Whether your branch is `fix/*` or `feature/*`, external contributors should **open pull requests directly against `main`**.
+
+Reasons:
+
+- `main` is the default branch, so the PR entry point is clearer
+- merged contributions are immediately visible on the default branch
+- maintainers can handle downstream sync and release preparation in one place
+
+Recommended flow:
+
+1. Fork this repository
+2. Create a branch in your fork (`fix/*` or `feature/*` is recommended)
+3. Make your changes and perform basic self-checks
+4. Push the branch to your fork
+5. Open a pull request against the `main` branch of this repository
+
+---
+
+## Pull Request Requirements
+
+Please keep each pull request focused, reviewable, and easy to validate.
+
+Recommended expectations:
+
+- one pull request should address one logical change
+- use a clear title that explains the purpose
+- include the following in the description:
+  - background and problem statement
+  - key changes
+  - impact scope
+  - validation method
+- include screenshots or recordings for UI changes when helpful
+- explicitly mention risk and rollback notes for compatibility, data, or build-chain changes
+
+---
+
+## Merge Strategy for Maintainers
+
+Pull requests merged into `main` should generally use **Squash and merge**.
+
+Reasons:
+
+- keeps `main` history clean and linear
+- maps each PR to a single commit on `main`
+- reduces release, audit, and rollback complexity
+
+---
+
+## Maintainer Sync Rules
+
+Because external pull requests are merged directly into `main`, maintainers must sync `main` back to development and release branches to avoid branch drift.
+
+### 1. Sync `main` -> `dev` (required)
+
+The automatic GitHub Actions sync workflow has been removed.
+Maintainers should sync `main` back to `dev` manually when needed:
+
+```bash
+git checkout dev
+git pull
+git merge main
+git push
+```
+
+### 2. Create `release/*` from `dev`
+
+Before a release, create a release branch from `dev`, for example:
+
+```bash
+git checkout dev
+git pull
+git checkout -b release/v0.6.0
+git push -u origin release/v0.6.0
+```
+
+### 3. Release from `release/*` back to `main`
+
+When release preparation is complete, merge the release branch back into `main` and create a tag:
+
+```bash
+git checkout main
+git pull
+git merge release/v0.6.0
+git push
+git tag v0.6.0
+git push origin v0.6.0
+```
+
+### 4. Sync `main` back to `dev` after release
+
+After the release, the same automation still applies. If needed, you can run the workflow manually (`workflow_dispatch`) or execute the fallback commands:
+
+```bash
+git checkout dev
+git pull
+git merge main
+git push
+```
+
+---
+
+## Commit Message Recommendation
+
+Keep commit messages clear and easy to audit.
+
+Recommended format:
+
+```text
+emoji type(scope): concise description
+```
+
+Examples:
+
+```text
+🔧 fix(ci): fix DuckDB driver toolchain on Windows AMD64
+✨ feat(redis): add Stream data browsing support
+♻️ refactor(datagrid): optimize large-table horizontal scrolling and rendering
+```
+
+---
+
+## Additional Notes
+
+- Please include validation results for documentation, build-chain, or driver compatibility changes
+- For larger changes, opening an issue or draft PR first is recommended
+- Maintainers may ask contributors to narrow the scope if the change conflicts with the current project direction
+
+Thank you for contributing.

+# 贡献指南
+
+感谢你对本项目的贡献。
+
+本项目采用“发布优先（`main` 为默认分支）+ `release/*` 分支发版”的协作模型。为减少分支漂移与 PR 处理成本，请在提交贡献前先阅读本指南。
+
+---
+
+## 分支模型
+
+- `main`：稳定发布分支，也是仓库默认分支
+- `dev`：日常开发集成分支，主要供维护者使用
+- `release/*`：发布准备分支，主要供维护者使用
+- 外部贡献者建议使用以下分支命名：
+  - `fix/*`：问题修复
+  - `feature/*`：功能新增或增强
+
+维护者发布流转如下：
+
+```text
+feature/* / fix/* -> dev -> release/* -> main -> tag(vX.Y.Z)
+```
+
+---
+
+## 外部贡献者如何提 Pull Request
+
+无论是 `fix/*` 还是 `feature/*`，**外部贡献者统一直接向 `main` 发起 Pull Request**。
+
+这样做的原因：
+
+- `main` 是默认分支，PR 入口更直观
+- 合并后贡献会直接体现在默认分支
+- 便于维护者统一做后续同步与发版整理
+
+建议流程：
+
+1. Fork 本仓库
+2. 从你自己的仓库创建分支（建议命名为 `fix/*` 或 `feature/*`）
+3. 完成代码修改，并进行必要自检
+4. 推送到你的远程分支
+5. 向本仓库的 `main` 分支发起 Pull Request
+
+---
+
+## Pull Request 要求
+
+请尽量保证 PR 单一、清晰、可审核。
+
+建议遵循以下要求：
+
+- 一个 PR 只解决一类问题，避免混入无关改动
+- 标题清晰说明改动目的
+- 描述中说明：
+  - 背景与问题
+  - 变更点
+  - 影响范围
+  - 验证方式
+- 如涉及 UI 调整，建议附截图或录屏
+- 如涉及兼容性、数据变更或构建链路调整，请明确说明风险和回滚方式
+
+---
+
+## PR 合并策略（维护者）
+
+`main` 分支上的 PR 建议使用 **Squash and merge**。
+
+原因：
+
+- 保持 `main` 历史干净、线性
+- 每个 PR 在 `main` 上对应一个清晰提交
+- 降低发布排查与回滚成本
+
+---
+
+## 维护者同步规则
+
+由于外部 PR 会直接合入 `main`，维护者必须及时将 `main` 的变更同步到开发与发布分支，避免分支漂移。
+
+### 1. main → dev 同步（必做）
+
+仓库已移除 GitHub Actions 自动回灌 workflow。
+当前统一采用手动方式将 `main` 同步回 `dev`：
+
+```bash
+git checkout dev
+git pull
+git merge main
+git push
+```
+
+### 2. 发版前从 dev 切 release/*
+
+发布前由维护者基于 `dev` 创建发布分支，例如：
+
+```bash
+git checkout dev
+git pull
+git checkout -b release/v0.6.0
+git push -u origin release/v0.6.0
+```
+
+### 3. release/* → main 发版
+
+发布准备完成后，将 `release/*` 合并回 `main`，并打标签发布：
+
+```bash
+git checkout main
+git pull
+git merge release/v0.6.0
+git push
+git tag v0.6.0
+git push origin v0.6.0
+```
+
+### 4. main 回流到 dev（发版后必做）
+
+发布完成后，仍沿用同一套自动化流程；如有需要，也可以手动触发 `workflow_dispatch`，或执行以下兜底命令，确保开发线与发布线一致：
+
+```bash
+git checkout dev
+git pull
+git merge main
+git push
+```
+
+---
+
+## 提交建议
+
+建议保持提交信息简洁、明确，便于维护者审查与后续追踪。
+
+推荐格式：
+
+```text
+emoji type(scope): 中文描述
+```
+
+示例：
+
+```text
+🔧 fix(ci): 修复 Windows AMD64 下 DuckDB 驱动构建工具链
+✨ feat(redis): 新增 Stream 类型数据浏览支持
+♻️ refactor(datagrid): 优化大表横向滚动与渲染结构
+```
+
+---
+
+## 其他说明
+
+- 文档、构建链路、驱动兼容性相关改动，请尽量附带验证结果
+- 若改动较大，建议先提 Issue 或 Draft PR，先对齐方案再实施
+- 如提交内容与项目当前架构方向冲突，维护者可能要求收敛范围后再合并
+
+感谢你的贡献。

-### macOS 提示 "应用已损坏，无法打开"
+### macOS: "App is damaged and can’t be opened"
 
-由于本项目尚未购买 Apple 开发者证书进行签名（Notarization），macOS 的 Gatekeeper 安全机制可能会拦截应用的运行。请按照以下步骤解决：
+Without Apple notarization, Gatekeeper may block startup.
 
-1.  将下载的 `GoNavi.app` 拖入 **应用程序** 文件夹。
-2.  打开 **终端 (Terminal)**。
-3.  复制并执行以下命令（输入密码时不会显示）：

-4.  或者：在 Finder 中右键点击应用图标，按住 `Control` 键选择 **打开**，然后在弹出的窗口中再次点击 **打开**。

-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。

+
+GoNavi 是基于 **Wails (Go)** 与 **React** 构建的跨平台数据库管理工具，强调原生性能、低资源占用与多数据源统一工作流。
+
+相比常见 Electron 客户端，GoNavi 在体积、启动速度和内存占用上更轻量。
+
+---
+
+## 项目简介
+
+GoNavi 面向开发者与 DBA，核心目标是让数据库操作在桌面端做到“快、稳、统一”。
+
+- **原生性能架构**：Wails（Go + WebView），降低运行时开销。
+- **大数据可用性**：虚拟滚动 + DataGrid 交互优化，提升大结果集可操作性。
+- **统一连接能力**：支持 URI 生成/解析、SSH 隧道、代理、驱动按需安装。
+- **工程化能力完整**：覆盖 SQL 编辑、对象管理、批量导出/备份、数据同步、执行日志、在线更新。
+
+## 支持的数据源
+
+> `内置`：主程序开箱即用。  
+> `可选驱动代理`：需在驱动管理中安装启用后可用。
