🤖 fix: expose setWorkspaceMetadata from WorkspaceContext

App.tsx needs to optimistically update workspace metadata when creating/forking
workspaces to avoid race condition with validation effect. WorkspaceContext now:

- Exposes setWorkspaceMetadata to allow App.tsx to update metadata immediately
- Updates metadata map immediately in createWorkspace before returning
- Passes through setWorkspaceMetadata in AppLoader instead of no-op

This ensures metadata is available when setSelectedWorkspace is called, preventing
the validation effect from clearing the selection before the async subscription fires.
