 * Retries a condition until it's met or timeout is reached.

 * @param options - Configuration options for retry behavior
 * @returns Promise that resolves to the condition result or undefined if timeout

 * @example
 * // Wait for a value to become available
 * const value = await retryUntil(
 *   async () => await checkCondition(),
