Level tasks across workers API

Assigns independent tasks to N identical parallel workers to minimize makespan using the LPT greedy heuristic, returning per-worker assignment, makespan, lower bound, and utilization. Answers 'How do I balance these tasks across my team to finish soonest?', 'What's the makespan with N workers?'.
