/**
 * Resolves an optional injected `[0,1)` generator, falling back to `Math.random` — and says so, once
 * per call site.
 *
 * Every primitive that rolls dice takes an `rng`, but the default was silent: a caller who forgot to
 * pass `ctx.rng` got a simulation that cannot replay, lockstep, roll back, or be pinned by a test,
 * with nothing on screen or in the log to say why. The fallback stays (a portable helper called
 * outside a game context is a real use), but it is now loud instead of invisible.
 *
 * @capability resolve-rng resolve an optional injected RNG, warning once per site when it falls back to `Math.random`
