chore: 同步 v5.0 基础设施完善到 v5.1

从 v5.0 cherry-pick 的开源项目基础设施改进:

新增配置文件:
- .editorconfig, .gitattributes, .prettierrc, .markdownlint.json
- commitlint.config.js

新增 GitHub 社区文件:
- .github/dependabot.yml — 依赖自动更新
- .github/CODEOWNERS — 自动 PR 审查分配
- .github/FUNDING.yml — 开源赞助入口

新增文档:
- ROADMAP.md — 路线图
- SUPPORT.md — 帮助指南
- docs/screenshots/ — 应用截图

新增 Git Hooks:
- .husky/pre-commit — lint-staged 自动格式化+修复
- .husky/commit-msg — commitlint 校验

CI 强化:
- 新增 Prettier 格式检查
- 新增 Vitest 覆盖率 + Codecov 上报
- 保留 v5.1 已有的 rust-cache + jsdom 全局环境

修复:
- index.html 标题 v4.0 → v5.1
- PathEditDialog set-state-in-effect 改用 useRef prevOpen 守卫
- merge-preview.test.tsx no-explicit-any 修复
- 所有 TS/TSX 文件 Prettier 格式化统一

v5.1 保留特性:
- @tanstack/react-virtual 虚拟滚动
- jsdom 全局测试环境
- Swatinem/rust-cache CI 加速
- 105 测试全部通过
