 * it and releases a retired workspace when the last call finishes. Retirement is synchronous and
 * is performed only while the manager mutex is held. Every skill-owned tool wrapper — module
 * tools, isolated JS tools and scripts alike — must close over this exact record rather than
 * consulting a registry, because hydrated wrappers can outlive the context they were registered
 * in: unregistering reaches only the context that requested the unload, so the record is the
 * authority on liveness and the registry is not.
