List the teamspaces (Spaces) the current user is a member of, within the token's workspace. Use this to resolve a teamspace before scoping other calls: each returned id (integer) is the value you pass as the Space header (or --space / space_id) to narrow a request to that teamspace.

The token stays bound to its one workspace — this does not switch workspaces, it only lists the sub-spaces you can scope into. Supports ?search=<name> to filter by teamspace name and ?expand=settings.

Each item: {id (int), name, slug}.
