/**
 * HomeView tests. Under the unified layout the chat is the right sidebar (owned by AppShell),
 * so HomeView is just the /agent context column: DisplayArtifactPanel, which shows the active
 * thread's open conversation/email/file, or the agenda by default. DisplayArtifactPanel is mocked
 * to a sentinel — it needs the full tRPC/canvas provider stack; this is a headless proof of the
 * layout composition.
