Leetcode 1767. Find the Subtasks That Did Not Execute

Given a directed hierarchy/DAG of tasks and their subtasks and a log of executed subtask IDs, identify which subtasks were never executed (including those unreachable through dependency chains). This requires graph traversal/marking or set-difference approaches that handle nested dependencies and large input sizes efficiently.
