feat(bat): 补全翻译工作台编辑命令

@@ -30,7 +30,7 @@ Rust 侧官方日服资源链路已经从实验验证推进到正式入口：
 13. 资源导入链路已支持 CAS + `ResourceRepository` 索引写入，官方同步可用 `--import-repository` / `BAT_IMPORT_REPOSITORY=1` 在已校验 release 发布后触发导入，默认 CAS 路径为 `<output>/.cas`、SQLite 索引为 `<output>/resources.sqlite`，也可通过 `--import-cas-root`、`--import-resource-db`、`BAT_IMPORT_CAS_ROOT`、`BAT_IMPORT_RESOURCE_DB` 覆盖；`resource.index` RPC/CLI 可按类型、hash、路径模式、官方 release ID、平台、destination、bundle path、archive entry、parse status 和 TextUnit format 分页查询现有索引，数据库不存在时返回 `available=false` 且不会创建空库。`Resource` metadata 已通过 `metadata_json` 兼容迁移保存 release、平台、bundle path、parse status、TextAsset 名称和 TextUnit 数量/格式；当前/上一个/结构变化 catalog、失败 staging 复用、403/404、hash mismatch、CRC、metadata 迁移与 UnityFS 边界校验均有离线回归 fixture 或单测覆盖。
 14. 非 dry-run 官方同步在校验完成并发布后，会先对比上一完整 release 与当前 release 的 `official-download-manifest.json`，在当前 release 下写入 `official-resource-changes.json` 和 `crowdin-translation-handoff.json`；同一 destination 只有 size 或 BLAKE3 改变才算 modified，仅 URL/CDN 根变化但内容相同不会触发解析/翻译候选。随后刷新 `official-parse-cache.json` 和 `official-textunit-index.json`，并从 Added/Modified 资源、parse cache 与 TextUnit 明细索引派生 `official-textunit-tasks.json` 和 `crowdin-textunit-queue.json`；删除资源只进入差异记录，不进入 TextUnit/Crowdin 队列。`parse.text_units` 和 `parse.errors` RPC/CLI 可按 destination、archive entry、path id、class id、field path 和 format 查询当前 release 的 TextUnit 明细与解析错误；`translation.tasks` RPC/CLI 可按 release、destination、archive entry、任务状态、parse status、TextUnit format 和 reason presence 查询离线 TextUnit 翻译任务状态与跳过/失败原因；TextUnit 已包含 class id、field path、字段 offset/byte size 等可追溯定位。Crowdin 当前仅预留本地离线队列，不发网络请求；up-to-date 轮询在已有有效解析缓存、TextUnit 明细索引和 TextUnit 队列时只读取摘要，不重复解析。官方同步报告默认 `localized_release_status=not_localized`，含义是原版资源已经发布、汉化资源未发布；UnityFS TextAsset patch 发布成功后会写 `localized-patch-manifest.json`，校验 hash/size/diff/rollback 后才允许 `localized.status` 返回 `status=published`、`status_code=localized.published` 和 `localized_release_status=localized`。`bat` 首次启动会在二进制所在目录释放 `.env` 配置模板（`0600`），之后每次启动自动加载（不覆盖已存在的环境变量），支持 `BAT_OUTPUT`/`BAT_LOCALIZED_OUTPUT`/`BAT_IMPORT_REPOSITORY`/`BAT_IMPORT_CAS_ROOT`/`BAT_IMPORT_RESOURCE_DB`/`BAT_STATE_DIR`/`BAT_AUTO_DISCOVER`/`BAT_WATCH`/`BAT_DAEMON`/`BAT_PROXY` 等键，实现编辑 `.env` 后无参启动；优先级为命令行参数 > 进程环境变量 > `.env` > 内置默认值，`BAT_SKIP_ENV_FILE=1` 可整体禁用；Redis 键为预留。daemon 任务历史持久化在 `<state-dir>/bat-tasks.json`（版本化、`0600` 原子写），重启后任务经 `task.*` 仍可查，中断任务标记 `task_interrupted`（`BAT-ERR-700005`）。
