feat(app-iced): M109 CONTENTDL —— 内容库页(整合包/Mod/资源包/光影)

用户令「下载页只负责下载整合包和Mod/光影」:新开一页做**内容发现与装入**,
检索走 Modrinth(优先,无需 key)/ CurseForge(`ULL_CF_API_KEY` 环境变量,日志只打
set/unset),装入走 core 的下载引擎真下到实例目录,进度/取消/失败复用下载页那块安装面板。

- **入口(B1)**:`Route::Content` 是新顶层路由,但 `Route::nav()` 复用 `NavSection::Download`
  ——导航轨仍五项,页头右上是「版本管理 | 内容库」一级切换(版本管理页也加了同一个切换,
  否则内容库只有 `ULL_START_ROUTE` 能到)
- **页内四条一级侧栏**(`pages/content/layout.rs` 四档几何:992/856/648 三个门槛都是
  「Σ栏宽 + 间距」算出来的):整合包 / Mod / 资源包 / 光影;标签栏 200(`Resource packs`
  比 M107 的版本类型名长,140 会切字,已登记偏离)
- **筛选**:关键词(草稿 + 显式「搜索」按钮,不逐字打网络)、来源、游戏版本、加载器
  (Fabric/Forge/NeoForge/Quilt)、排序;**分页**(「加载更多」)而不是无限滚动——快照只有一个槽、
  翻页要看得见、状态要可截图复现
- **四态**:加载 / 空 / 失败 / 有数据 + 「没有更多了」;筛选条在任何状态下都在(加载中藏筛选条
  等于把入口收走)
- **一键装入**:`Content::blockers()` 是纯函数——版本不匹配、加载器不匹配、没有目标实例、
  整合包缺管线**四条原因逐条**给出,按钮点之前就禁用;判定与画法分开(model/tests 直接钉)
- **整合包今天不可装**:`ContentKind::Modpack.dir()` 是 `None`,UI 禁用 + 说明,host 侧再挡
  一次(绕过 UI 也只会回一条 Failed)。真流程是 M111 的导入管线
- **零 UI 网络**:`presenter/host/addon.rs` + `addon/{sources,http,install}.rs`;无 header 的请求走
  core 的 `download_bytes`(信号量限流 + 健康度 + 退避全现成),带 `X-API-KEY` 的只有 CF 一条,
  自带 429/5xx 退避(优先吃 `Retry-After`,封顶 30s);密钥不进 DTO/日志/仓库
- 文案 41 条中英进 `crates/i18n`(新域接在装配链末尾 ⇒ `Key::ALL` 与金表只追加)
- 演示数据 `ContentHit → Hit::of` 与产品路径同源(格式化不会两套),`ULL_CONTENT_KIND` /
  `ULL_CONTENT_STATE` 供出图矩阵选类型与状态

取证:`DevDocs/artifacts/m109/`(10 张:四类内容 × 浅/深 + 搜索无结果 + 加载器不兼容禁用)

门禁:fmt ✓ / clippy `-D warnings`(三 crate)✓ / app-iced 450+6、presenter 170、i18n 24 全绿;
`cargo tree` 两条零 UI 门禁仍空;全部改动文件 ≤400 行。

//! 内容库视图模型的守门测试(M109):四态判定、兼容性判定、装入闸门。
//!
//! 全部是纯函数级断言(不开图形环境):`status_of` / `blockers_of` / `Content::can_install`
//! 是页面「该画什么、按钮能不能按」的唯一判据,钉住它们比截图更早期。
