/**
 * The agent behind `useResource` / `useSuspenseResource`: one agent per
 * `(resource, args key)`, created during render and started after commit.
 *
 * Render stays pure on purpose. Mutating a single long-lived agent from render
 * (`agent.set(args)`) is a side effect on a store shared by every render of the
 * component — including the concurrent ones React keeps in flight at the same
 * time. With an args change inside a transition, the transition render pushes
 * the new args into the store, the store notifies, React synchronously
 * re-renders the *committed* tree (still on the old args), which pushes the old
 * args back, and so on until the transition times out. A fresh agent per args
 * gives every render lane its own object: nothing is shared, nothing loops.
 *
 * SWR across an args change is preserved by handing the stale data over from
 * the last committed agent to its successor (`adoptPrevious`). The handoff
 * source is a ref written in the layout effect, so a discarded render never
 * leaks into the committed tree and a successor always continues from what is
 * actually on screen.
 *
 * @param startDuringRender - Start the query when the agent is created (the
 *   Suspense hook: a suspended render aborts its effects, so a deferred start
 *   would leave the fallback hanging forever). Otherwise the query starts in a
 *   layout effect, once the render is committed.
