Leetcode 1834. Single-Threaded CPU

Given tasks with enqueue and processing times, return the order a single-threaded CPU will process them when it always picks the available task with the smallest processing time (tie-broken by original index). This is typically solved by sorting tasks by enqueue time and using a min-heap to manage available tasks and advance time when the CPU is idle.
