/**
 * The session-rename assembly chain on SlotTestRuntime (real apply, real
 * WorkspaceBrowser occupying the sidebar hole): row menu → rename dialog →
 * the injected renameSession hop (sessions.binding → ISession.rename) → on
 * the accepted unary response the dialog closes and the row re-labels from
 * the list state — no push-frame wait. Previously pinned only by the
 * assembled-app snapshot (apps/web/tests/session-actions.snapshot.ts); the
 * verb's wire behavior stays with the runtime package
 * (session.spec.ts#rename), the dialog's own arms with rows.spec /
 * workspace-browser.spec.
