chore: 开源项目基础设施全面完善

新增配置文件:
- .editorconfig — 跨编辑器代码风格统一
- .gitattributes — 行尾符 CRLF 规范化
- .prettierrc + .prettierignore — 前端代码格式化
- .markdownlint.json — Markdown 格式规范
- commitlint.config.js — Conventional Commits 强制校验

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

新增文档:
- ROADMAP.md — v5.1/v5.2/v6.0 路线图
- SUPPORT.md — 帮助与支持指南
- docs/screenshots/ — 截图目录就位

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

CI 强化 (.github/workflows/ci.yml):
- 新增 Prettier 格式检查步骤
- 新增 cargo fmt --check 步骤
- 新增 Vitest 覆盖率生成 + Codecov 上报

修复:
- index.html 标题 v4.0 → v5.0
- PathEditDialog set-state-in-effect 改用 useRef prevOpen 守卫
- use-app-actions.test.tsx 缺失 @vitest-environment jsdom
- 所有 TS/TSX 文件 Prettier 格式化统一

配置更新:
- vitest.config.ts — v8 覆盖率 + 阈值门禁 (60%/70%)
- package.json — format/format:check/test:coverage/prepare 脚本 + lint-staged
- .gitignore — 新增 coverage/sync-conflict/playwright-report
- README.md — 新增 coverage + platform 徽章 + 截图区域
