release: v0.2.0 — TypeScript 源码重构

### Changed
- 全部源码从 JavaScript 迁移到 TypeScript (strict mode)
- core.js (1244行) 拆分为 toast.ts + api.ts + templates.ts
- 删除手动维护的 types/index.d.ts，类型从源码自动生成
- 构建工具链: Babel → ts-jest, 新增 @rollup/plugin-typescript
- 新增 rollup-plugin-dts 生成合并 .d.ts

### Added
- tsconfig.json (strict: true)
- src/types.ts 核心类型模块 (39 个导出类型)
- .eslintrc.json (@typescript-eslint)
- .gitea/workflows/ci.yml (Node 18/20/22/24 矩阵)
- CHANGELOG.md

### Aligned with metona-starter
- package.json: type:module, engines≥16, prepublishOnly
- rollup.config.js: dts plugin, port 3001
- jest.config.cjs, build.sh, serve.sh, .gitignore (.npmrc)

### Removed
- babel.config.js, types/ 目录, 所有 src/*.js

package.json
