/**
 * Create an async computed ref.
 *
 * Returns a ref whose value is the result of an asynchronous evaluation function.
 * Since STX async computations use explicit dependencies, you can
 * provide an optional array of dependency refs. When any dependency changes,
 * the evaluation callback is re-run.
 *
 * @param evaluationCallback - An async function that returns the computed value
 * @param initialState - The initial value before the first evaluation completes
 * @param deps - Optional array of reactive refs to watch for re-evaluation
 * @returns A ref containing the async computed value
 *
 * @example
 * ```ts
 * const userId = ref(1)
 * const user = computedAsync(
 *   async () => {
 *     const response = await fetch(`/api/users/${userId.value}`)
 *     return response.json()
 *   },
 *   null,
 *   [userId],
 * )
 * ```
