feat(scripts): 跨 owner 懒加载目录树 + 跨用户可见 workspace/public

修两个后端接口问题: 1) /api/v1/workspace-directories 返回为空,目录树结构消失 2) 同 workspace 内脚本/数据互相可见但默认排除 private 后端改动 -------- * list_scripts / list_resources / list_workspace_directories 新增 owner_user_id 可选 query 参数;缺省 = 当前请求者本人(scope 到 workspace/{me}/...),传值时 scope 到该 owner 的子树。前端根加载默认只见自己一级,其他成员以折叠分组呈现。 * visibility 过滤统一:非 admin 请求者只返回 owner==me 或 visibility ∈ {workspace, public};admin 跳过。owner=me 含自己的 private,owner=other 只剩其 workspace/public,排除他人 private。 * create_workspace_directory 两个分支 visibility 默认 'public' (非 private),使跨 owner 目录树可见;响应新增 owner_user_id 字段。 * platform.list_members 鉴权从 system_admin_context 放宽为系统管理员或该 workspace 活跃成员(让普通用户也能渲染同 workspace 成员名册,用于跨 owner 分组)。 * main.py 注册 platform 模块(随 list_members 改动补齐导入)。 * .env.example 同步 common/config.py 26 个字段。前端改动 -------- * ScriptExplorer.memberScriptGroups 改由 members 列表播种分组, display_name 取 members.display_name;inferredDirectories 现在按 owner_user_id 标记,统一跨 owner 目录渲染。删除脚本目录页头与树分组标题的工作副本数量角标。 * WorkspaceTree 新增 ownerUserId 透传到 store.toggleExpanded; 仅"我"的分组 mount 时 auto-expand,他人分组默认折叠,展开才调 loadOwnerGroup / owner-scoped loadScripts / loadChildren。 * scriptWorkspaceStore 引入 namespaced cache key (ownerCacheKey = `${ownerUserId ?? me}:${path}`),loadedScriptPaths / loadedChildPaths / loadedOwnerGroups 全部按 owner 隔离; toggleExpanded 用 loadPath === undefined 区分 group 头与真实目录,修"他人子目录点击不触发接口"的 loadPath 前缀误判 bug。 * api.ts / AuthContext 透传 ownerUserId 给 listScripts / listResources / listWorkspaceDirectories。文档 ---- * API.md: §3.2 创建目录 visibility 默认 public + 响应加 owner_user_id; §3.3.1 GET directories 加 owner_user_id 参数 + 响应字段; §3.4 GET scripts 改写为 owner 作用域 + visibility 过滤语义; §五.1 GET data-resources 新增,同一套统一语义; §7 intro 例外 — GET members 对系统管理员或 workspace 活跃成员开放。 * DEVELOP.md: Code layout 重写以反映 backend api/services/clients/ schemas 拆分 + schedule domain/scheduling/application/execution/ infrastructure 拆分 + common 子包(auth/storage/backends); Configuration 系统补全 26 个 settings 字段;新增 "Owner-scoping + visibility (cross-owner browsing)" 小节; Per-service dev 注释用 uv run 的源布局要求;Add a new DAG endpoint / storage bucket 路径改为 backend/src/backend/api/* 与 services/*。测试 ---- * test_list_scripts_parent_path.py / test_resources.py 补充 owner_user_id 参数化直接调用 + LIKE 前缀断言(workspace/{owner}/... 前缀)。 Co-Authored-By: Claude <noreply@anthropic.com>
