feat(game): 从其他启动器只读登记已有版本（ull instances scan|adopt）+ 登记可一并定隔离档（M221）
盘上已经铺好的版本（多半是 PCL/HMCL 装的）今天在 ULL 里看不见，用户只能重装一遍。这个 commit 把它们登记成实例，**只读外部、只写自己的配置**：不搬文件、不补清单、不改任何外部 文件的 mtime（versions/ libraries/ assets/ 一个字节都不写）。 core（`game::adopt`，新模块）： - `scan` / `inspect`：只读扫描 + 逐项检查，坏 JSON（带行列号）/ 缺 id / id 与目录名不一致 / 缺父 / 成环 / 读不出来 / 越界 / 同名冲突一律**结构化**报错（稳定 `code`），不吞成空列表； `versions/` 不存在才是空结果，读不了就是错误； - 越界判据用 canonicalize 后的前缀比较，同时覆盖**符号链接、Windows 目录联接（junction）与 祖先链接**（junction 不需要管理员权限，是最常见的「把别人版本目录挂进来」）；越界条目在 边界检查就停手，一个字节都不去读； - `plan`（零写盘，喂 dry-run 与后续 GUI 预检）/ `adopt`（plan + 只写自己的配置）： **缺省运行目录落 ULL 数据区 `<data>/instances/<实例目录名>`（custom 档），绝不沿用全局 `isolated`**——那条缺省的运行目录正是 `versions/<versionId>/`，会在他人的版本目录里长出 mods/saves/config；`shared` / `isolated` 必须显式选，且 `target_notes()` 给出后果话术； - 缺省运行目录已存在且非空 ⇒ 拒绝（不覆盖、不猜「合并进已有实例」）；数据区里已有的祖先 若解析到数据根之外（符号链接/联接）⇒ 拒绝，不沿它写盘； - 登记与隔离档一次写清：`install/instance` 拆出 `register` 子模块，新增 `register_with(InstanceSettings)`；写盘顺序改成「先实例设置、后 profiles」（中断只留孤立 设置文件，不会留下按全局档启动的实例），profiles 写失败会撤掉刚写的设置。`register` 签名与行为不变（`register` = `register_with(inherit)`；同版本同名的幂等复用照旧）。 CLI： - `ull instances scan`（只读列出候选与原因）、`ull instances adopt <version-id> [--name N] [--isolation shared|isolated|custom] [--game-dir DIR] [--dry-run]`；`--game-dir` 单独给即 custom，相对路径在解析期就报用法错误； - 人读/`--json`/help 三条出口齐备（`error.detail.problems` 逐条可分流），已有命令未改。 测试（真磁盘夹具，`cargo test -p unlucky-core --test adopt` 22 passed / `cargo test -p unlucky-cli --test adopt_test` 10 passed）： - 一份「别的启动器铺好的」`.minecraft`（versions/libraries/assets/mods/saves/config + launcher_profiles.json），扫描与登记前后做「路径集合 + 字节数 + 内容哈希 + mtime」全等断言； - 正常 / 缺清单 / 坏 JSON / 缺父 / 成环 / id 不匹配 / 非法 id / 符号链接越界 / 根内符号链接 放行 / **junction 越界** / 数据区 junction 写盘边界 / 缺省非 isolated / shared 与 isolated 的话术 / 重名 / 重复 / 非空目录 / 空目录复用 / dry-run 零写盘； - CLI 侧验 `launch --dry-run` 的 `--gameDir` 指向选定运行目录（argv 已脱敏，比尾段； `data.game_dir` 全等）； - 变异核对（只改实现、跑完即回滚）：缺省档改 `VersionDir` ⇒ 红；边界判据摘掉 ⇒ 符号链接与 junction 两条红；写盘边界摘掉 ⇒ 数据区 junction 那条红；缺父当链终点 ⇒ 两条红。 界限：没有启动真实 Minecraft；GUI（presenter/app-iced）接线另派；D20 单游戏根模型未改 （不扫第二个 `.minecraft`）。
