/**
 * Pure async-generator factory for `race`. Returns a 0-arg generator
 * function; calling it once produces the async iterator the runtime wrapper
 * hands to `readableFrom` / `ReadableStream.from`.
 *
 * @typeParam T — element type of output values.
 * @param pullers — non-empty array of async iterators. Validation is the
 *   wrapper's responsibility; `raceGen` trusts its inputs.
 * @param options — currently unused; reserved for future per-component
 *   options.
 * @returns a 0-arg async-generator function.
