/**
 * Laya Provider — the `decide` inference type only.
 *
 * Laya is Convai Innovations' open-weights "System One" decision model: the
 * same typed `noul` / `choice` / `score` questions as TypeSafe's Jev, answered
 * by an encoder in one forward pass, on the same wire. The request loop,
 * retries, auth circuit breaker and answer parsing are shared with every
 * decision provider in {@link SystemOneDecisionProvider}.
 *
 * Its encoders read far less than Jev: 1,024 tokens on the `typed-decisions`
 * and `multilingual` checkpoints, 512 on `english`. The descriptor's
 * `decisionLimits` refuses what does not fit rather than letting the server
 * cut the state off silently.
 *
