feat(office): Office 技能在 Desktop、Web、SDK 均可用

- Office 技能从 Desktop 专属改为在 Web、SDK 与 Desktop profile 中均可挂载
- skill-office 新增 pythonEnvironment 配置，按部署显式选择内置依赖或用户已有的 Python
- Python 类技能末尾追加固定的 Python 环境说明，技能正文不再写死 load_workspace_dependencies
- 去掉 node:sea 探测，避免 Web 预览镜像依赖 webworker stub

 `DSH_RESOURCE_CACHE` selects an absolute cache root, defaulting to `~/.cache/deepseek-harness/resources`. Resource identities include the release's locked inputs. Downloads verify archive hashes and package identities, preserve executable permissions, and publish completed directories atomically. Failed downloads can be retried. `DSH_RESOURCE_DOWNLOAD_TIMEOUT_MS` bounds each archive download, including its body; the default is `300000`, and accepted values are integers from `1` to `2147483647`. Downloads follow the Harness proxy environment policy. Installed wheel files are never modified. Release versions have separate cache directories; unused versions require manual removal. Downloads use the locked upstream URLs without a registry or mirror override.
 
-On subsequent launches the packaged bootstrap exposes downloaded resources to the SDK profile. `DSH_PRIMARY_RUNTIME` overrides the cached authoring environment; an empty value disables its query and package-manager selection. `DSH_OFFICE_SIDECAR` can select an absolute sidecar directory with its standalone Node. Users may provide their own Python environment and document libraries without downloading the authoring environment. Office skills are available when either resource is selected; authoring-only deployments expose the skills with the Kit CLI disabled. External authoring payloads retain the `primary-runtime/` plus sibling `office-skills/` layout. The SDK reads resources in place without copying them into `DSH_HOME`. The `sdk-minimal` profile does not mount these providers.

Users may provide their own Python environment and document libraries without downloading the authoring environment. Office skills are always available: with the authoring environment they direct the model to its bundled Python and libraries, and without it to the user's existing Python. Without a selected Office sidecar the skills report the Kit CLI as disabled. External authoring payloads retain the `primary-runtime/` plus sibling `office-skills/` layout. The SDK reads resources in place without copying them into `DSH_HOME`. The `sdk-minimal` profile does not mount these providers.
 
 Skill selection is independent of delivery: project, custom-directory, and user filesystem skills override same-name bundled skills. An SDK patch can disable only the Office provider while retaining the Python query:

 `DSH_RESOURCE_CACHE` 指定绝对缓存根目录，默认为 `~/.cache/deepseek-harness/resources`。资源身份包含发布版本锁定的输入。下载会校验归档哈希和包身份、保留执行权限，并原子发布完整目录。下载失败后可重试。`DSH_RESOURCE_DOWNLOAD_TIMEOUT_MS` 限制每个归档的下载耗时，包含响应内容；默认值为 `300000`，接受 `1` 到 `2147483647` 的整数。下载遵循 Harness 代理环境策略。已安装的 wheel 文件不会被修改。不同发布版本使用独立缓存目录；不再使用的版本需手动删除。下载使用锁定的上游 URL，不提供 registry 或镜像覆盖。
 
-后续启动时，打包 bootstrap 将已下载资源提供给 SDK profile。`DSH_PRIMARY_RUNTIME` 覆盖缓存中的创作环境；空值禁用其查询和包管理器选择。`DSH_OFFICE_SIDECAR` 可选择包含独立 Node 的绝对 sidecar 目录。用户可自行提供 Python 环境和文档库，无需下载创作环境。选择任一种资源即可使用 Office skills；仅有创作环境时，skills 中的 Kit CLI 被禁用。外部创作载荷保留 `primary-runtime/` 及同级 `office-skills/` 布局。SDK 原位读取资源，不复制到 `DSH_HOME`。`sdk-minimal` profile 不挂载这些提供方。
