/**
 * Run a list of async tasks with bounded concurrency.
 *
 * Unlike Promise.all(list.map(...)) this never schedules more than
 * `limit` tasks in flight at once — useful for fanning out over many
 * target languages without each one spinning up its own chat pool
 * before the first language has finished.
 *
 * When `limit` is 1 the behaviour collapses to serial execution,
 * matching the current default so existing workflows don't change.
 *
 * Errors are surfaced via Promise.allSettled semantics: every task
 * runs to completion, and the returned array preserves input order.
