PR Summary

Medium Risk
Introduces a new folder resource/context type across UI and chat APIs, including server-side context resolution that queries the DB; mistakes could break chat context serialization or degrade performance for large folders.

Overview
Adds Folders as a first-class selectable resource in the home “mothership” UI and copilot/mothership chat plumbing.

This extends resource/type enums and request schemas to accept folder, updates context serialization/mapping and tab name lookups, and adds cache invalidation for folder lists.

It also adds an embedded folder tab view (with a new Folder icon) that lists workflows in the folder, and enables agent context generation for folder attachments by resolving folder + workflow list content server-side.

Greptile Summary

This PR adds folders as a selectable resource type in the workspace resource menu (plus menu and add-resource dropdown), embedding a live folder view that lists contained workflows as clickable links opening in a new tab.

Key changes:

• Extended all resource type discriminated unions (MothershipResourceType, ChatContext, AgentContextType, Zod schemas across three API routes) to include 'folder'
• New resolveFolderResource(folderId, workspaceId) server function with workspace scoping on both the folder and workflow DB queries, wired into processContextsServer and resolveActiveResourceContext
• New EmbeddedFolder component rendering a workflow list per folder with a folder-not-found fallback state, using existing useFolders + useWorkflows queries
• RESOURCE_INVALIDATORS entry for folder invalidates folderKeys.lists() on resource_added SSE events
• useResourceNameLookup extended to keep folder tab names in sync after renames
• mapResourceToContext handles the new 'folder' case, producing { kind: 'folder', folderId, label }
• New Folder SVG icon added to the EMCN icon library
• Previously flagged workspace-scoping vulnerability in resolveFolderResource has been correctly fixed: both the folder lookup and the workflows lookup include eq(*.workspaceId, workspaceId) filters

Confidence Score: 5/5

Safe to merge — workspace scoping is correctly applied in resolveFolderResource, all type unions are consistently extended across every layer, and the embedded UI follows established component patterns.

No P0 or P1 issues found. The previously flagged workspace-scoping security concern has been addressed: both DB queries in resolveFolderResource filter on workspaceId. Type extensions are complete and consistent (Zod schemas, TypeScript unions, Zustand store types, React Query interfaces). EmbeddedFolder follows the exact same structure as EmbeddedWorkflow and EmbeddedFile. Cache invalidation and name-lookup hooks are properly updated.

No files require special attention.

Fixed in 6471057 — added case 'folder' to the overlayContent switch and imported Folder as FolderIcon from @/components/emcn/icons. Folder mention chips now render with the folder icon.
