fix: 修复跨实例同步移植的首轮编译错误

- re-export 可见性：synced_options_path 改从 files 导入；SyncedOptionJoinResolution 改从 pending 导入

- bind 移动语义：18 处 .bind(x) 改为 .bind(&x)（metadata.instance.id / option_id / custom_id 等）

- storage.rs：SqliteRow 字段访问改为 row.get()

- modpack.rs：去掉 Axolotl 独有的 DownloadMeta/DownloadReason，改用本地 5 参数 fetch

- state/mod.rs：补齐第 2 处 State 初始化的新增字段
