Balance a list of task durations across a specified number of workers to minimize the maximum workload per worker. Return a list of lists where each inner list contains the tasks assigned to one worker. Use a greedy approach to always assign the next task to the worker with the currently smallest total workload.
Examples:
List<Integer> tasks = new List<Integer>{3, 1, 4, 1, 5};
List<List<Integer>> balanced = balanceSchedule(tasks, 3);
// Results: [[5], [4], [3, 1, 1]] or similar balanced distribution
