显示安装按钮前设置当前语言文本。
下载完成后，代码只显示 #install-update。该按钮的初始 HTML 文本是中文，因此英语会话会显示“安装并重启”。
在设置 installButton.hidden = false 前，使用 t("Install and Restart") 写入按钮文本，并确保该消息键存在。

PR Title: feat(i18n): add English and Chinese localization Commit: 本次 PR（fix(i18n): preserve runtime state on language changes）将设置页更新卡片渲染重构为基于 updatePresentation 判别联合状态机的集中式 renderUpdatePresentation()，并在 applyLanguage() 中于 translateDocument() 之后重渲染更新卡片与 #current-version，从而在切换语言时既保留下载/安装等运行时状态、又完成新语言的翻译。逐一核对各状态（idle/available/checking/current/downloading/ready/check-error/installing/install-error）的按钮显隐/禁用、进度条宽度、progress 显隐与 card.data-state，均与旧行为一致；translateDocument() 先于 renderUpdatePresentation() 执行，避免更新卡片上 data-i18n 默认文案覆盖运行时状态，顺序正确，未发现设置页回归。新增 e2e 用例覆盖“下载完成后切换语言仍保持 ready 状态”。pet-debug 页新增 agent-cat-config-changed 监听以实时应用语言；messages.json 修复一处中文文案。主要问题：pet-debug 的实时语言应用不完整——loadPet() 烘焙进 #debug-validation 的动态译文与原生 i18n（sync_native_i18n）不会随语言切换刷新，导致调试窗口出现新旧语言混杂。 |

pet-debug 页切换语言后动态校验信息与原生标题不会随语言更新
本次改动为 pet-debug 页新增了 agent-cat-config-changed 监听，在语言变化时调用 applyLanguage() 实时应用新语言。但该 applyLanguage() 仅执行 setLanguage() 与 translateDocument()。translateDocument() 只处理带 data-i18n 的静态元素；而 loadPet() 通过 validation.innerHTML = ... + t(...) 写入的宠物校验信息（如「尺寸正确」「未使用格完全透明」等）是在加载时烘焙的译文，不带有 data-i18n，切换语言后不会刷新。此外，settings.ts 的 applyLanguage() 会调用 sync_native_i18n 同步原生窗口标题等，而 pet-debug 的 applyLanguage() 未调用，因此调试窗口的原生标题（Agent Cat Animation Tester）也不会更新。结果是打开调试窗口时切换语言，会出现静态文案已翻译、而 #debug-validation 校验块与原生标题仍停留在旧语言的中英文混杂状态，与本次“保留运行时状态并重新翻译”的目标不一致。
Problem code:
Changed code at src/pet-debug.ts:18-22
Recommendation:
在 pet-debug.ts 的 applyLanguage() 中补齐动态内容与原生 i18n 的刷新：与 settings.ts 保持一致调用 void invoke("sync_native_i18n", { value: nativeMessages() })，并在 pets 已加载时对当前宠物重新执行 loadPet(Number(select.value)) 以重渲染 #debug-validation 中的译文（或将这些文案改为 data-i18n 以复用 translateDocument）。

背景
Agent Cat 目前的用户界面文案主要直接写在 HTML、TypeScript 和 Rust 原生菜单中，无法根据用户语言切换。这个 PR 引入一套轻量的 i18n 基础设施，首期支持英文和简体中文，并保持现有配置和多窗口行为兼容。
