用户原话：「我们内置了那么多镜像源 甚至用户不能手动选择指定版本下载。」
「自动下载 jdk17 作为基准版本，后续在设置中提供多版本可供用户下载。」
- core：新增 `game::java::catalog`（8/11/17/21/25 五档 × 能承接的发行版 × 「该装哪档」），
数据全部来自 `JdkVendor::supports` 与 `vendor::order`，不复制第二份真相。
- progress：`SourceFailed` 补一个结构化的 `kind`（在这之前只有中文 `reason`，双语界面
要么放弃语言、要么放弃「哪个源为什么退避」这条用户可见信息）。
- app-iced：`downloads` 模块真下（后台线程 + `ProgressEmitter` + 快照），三态（选择列表 /
下载中 / 失败）都能说出「命中的源 / 退避原因 / 试过哪些源」；成功后重扫并（在
`java.auto_install` 开着且没有默认 JDK 时）把新装的那份设为默认。
- 三个设置键做成可改 UI：`java.installRoot` / `java.vendorPriority` / `java.auto_install`，
各自带「现在生效什么、从哪一层来」（数据目录模式 / 地区默认序），改完回读落盘值。
- `State::satisfied` 换成带方向的 `Fit`：1.12.2 + Java 21 不再被说成「低于要求」。
- i18n：删掉 `SettingsJavaEmptyBody` / `SettingsJavaAddHint` 的 markdown 反引号；
`SettingsJavaNeverScannedBody` 改成不与首屏自动扫矛盾的表述。
- 出图三张（选择列表 / 下载中 / 失败）在 DevDocs/artifacts/m197/。
顺带拆文件守 400 行：`golden/tail.rs` 的 M174 段搬到 `golden/tail_ai.rs`，
`pages/settings/java/{context,prefs,prefs_store,downloads,download_view}` 各自成模块。
