/**
 * ChatAgentPicker — the connected {@link AgentPicker}. Fetches the project's
 * agents with {@link useAgents} and renders the picker only when there is more
 * than one to switch between, so it can be dropped straight into the composer's
 * `toolbarStart` slot without the caller wiring up data:
 *
 * ```tsx
 * const [agentId, setAgentId] = React.useState<string>();
 * <ChatInput
 *   …
 *   toolbarStart={<ChatAgentPicker value={agentId} onValueChange={setAgentId} />}
 * />
 * ```
 *
 * It renders nothing while loading, on error, or when the project exposes fewer
 * than `minAgents` (default 2) agents — a single-agent project has nothing to
 * switch to, so the slot stays empty. Selection is controlled by the caller
 * (`value` / `onValueChange`), matching {@link AgentPicker}.
 *
