/**
 * After a successful shield broadcast, poll `onShielded` on a backoff
 * schedule so the consumer sees both the shielded and unshielded balances
 * update without a manual refresh click. Stops early on cancel or when
 * the optional `hasConverged` predicate returns true; swallows
 * per-iteration errors (refresh is best-effort).
 *
 * `isCancelled` is a thunk so callers can hook it up to whatever liveness
 * signal they have (effect cleanup `cancelled` flag, abort signal, mount
 * ref, etc.) without this module having to know about React lifecycle.
 *
 * `hasConverged` is optional and lets callers exit early once the
 * post-shield state has actually materialized (e.g. the just-shielded
 * token's unshielded balance has dropped). When omitted, the schedule
 * runs to completion. Checked both before each delay and after each
 * refresh so a refresh that produces the converged state ends the loop
 * immediately.
