release: v0.5.0 — 覆盖率96.42%达标、lint零警告、覆盖率门禁、CI强化、发布自动化

- 覆盖率 96.42%（行）：新增 59 测试共 385 个，覆盖 DOM 交互事件、对话框按钮交互、Intl/localStorage 异常路径、React 渲染生命周期
- 测试环境重构：SSR 分支用 defineProperty 真正覆盖 document/window；新增 tests/dom.test.ts、tests/setup.ts
- jest 覆盖率门禁 lines >= 95%；CI lint 改必过；新增 publish.yml（v* tag 自动发布到 Gitea registry）
- 修复：Toast.off 空数组残留、Toast.on 取消函数 this 绑定、action close:false 冒泡关闭、use() 重复注册钩子、i18n catch 引用错误
- 删除死代码 autoApplySystemTheme；lint 零警告（no-console 策略 + caughtErrorsIgnorePattern）
