/**
 * WorkspacesService talks to the agent-server's /api/workspaces endpoints,
 * which persist the user's saved workspaces and workspace parents on the
 * server (workspace/.openhands/workspaces.json). All clients pointed at
 * the same agent-server see the same list.
 *
 * The SDK WorkspacesClient owns compatibility preflight behavior, so old
 * agent-server backends surface the same typed version error without this
 * frontend constructing a raw HttpClient.
