refactor(office): Office 技能统一读取包内 assets，移除包外 office-skills 拷贝与 DSH_BUNDLED_OFFICE_SKILLS

- web-app、sdk-app 的 skill-office 不再覆盖 assetRoot；pythonEnvironment 不变
- Desktop 与 Python SDK 打包不再生成 office-skills 资源目录，删除 prepareOfficeSkillAssets 与 skillSource
- Desktop 打包 smoke 校验 4 个 Office 技能可从运行时归档列出并加载
- 同步测试、README、Agent Note，新增升级指南 office-skill-resources
