fix: improve i18n translation strings based on code review

Refactored translation strings to follow best practices:

1. Removed HTML tags from translation strings (en/chat.json)
   - Changed "Adds <span class=\"font-mono\">{{entry}}</span>" to "Adds {{entry}}"

2. Simplified TasksSettings.jsx component (TasksSettings.jsx)
   - Moved command code directly into translation file

3. Updated both English and Chinese translation files
   - en/chat.json: Removed HTML markup from permissions.addTo
   - zh-CN/chat.json: Corresponding Chinese translation update
   - en/settings.json: Added task-master init command
   -zh-CN/settings.json: Added task-master init command in Chinese

根据代码审查改进 i18n 翻译字符串：

1. 从翻译字符串中移除 HTML 标签（en/chat.json）
   - 将 "Adds <span class=\"font-mono\">{{entry}}</span>" 改为 "Adds {{entry}}"

2. 简化 TasksSettings.jsx 组件
   - 将命令代码直接移到翻译文件中

3. 更新英文和中文翻译文件
   - en/chat.json: 从 permissions.addTo 移除 HTML 标记
   - zh-CN/chat.json: 对应的中文翻译更新
   - en/settings.json: 添加 task-master init 命令
   - zh-CN/settings.json: 添加 task-master init 命令的中文翻译
