feat(sync): 接入解析缓存与汉化发布前置

补齐官方 release 解析缓存、TextUnit 明细索引、资源变更集、Crowdin handoff 预留、ResourceRepository 导入元数据和 localized release patch 前置链路。

同时开放文件级 patch.apply 与 UnityFS TextAsset/string/semantic field patch CLI/RPC 入口，并保留官方原版资源与汉化产物双目录发布状态。

验证：cargo test -p bat-assetbundle --locked；cargo clippy -p bat-assetbundle --all-targets --locked -- -D warnings；cargo test -p bat-infrastructure --locked。
