// 设置页右栏的「schema 分组」渲染器：下载 / Java / 数据 / AI / MCP 五组。
//
// 行来自 Rust 侧的 `SettingGroupView`（core::setting schema 的键），这里只按控件类型画：
// 开关 → toggle；分段 → segmented；文本 → text；只读 → 纯文案；动作 → 按钮。
// 写回一律 `PageState.setting-changed(key, value)` / `setting-action(action)`，
// 由 host 走 `SettingStore::set`（同源 launcher.json）。
