// <StatusChips> — the agent page's status row: the consolidated status
// badge (alive/thinking/paused/etc., with pause/resume + cancel-turn in
// its dropdown), the model and effort (display-only: the swarm sets
// them), and context/cost usage.
// This is the concrete fix for the design guide's own named anti-example
// (the old page's model/effort *pickers* lived in the `⋯` overflow menu
// while the current model/effort only showed as a disconnected chip) —
// every badge here IS the control for what it displays, composed from
// `@hive/shared`'s `Badge`/`Dropdown` (../../shared/src/badge,
// ../../shared/src/dropdown). Presentational only: formatting +
// selection state live in the caller (`Root.tsx`, via the
// `useAgentState` hook), so this component can still be demoed and
// reviewed against plain sample data independent of live `/api/state`.
