Reverse a singly linked list with optimizations.
AI-Expanded — inferred from the question title, not from the original candidate report
Given the head of a singly linked list, write a function to reverse the order of the nodes in-place. Your implementation should achieve this with O(n) time complexity and O(1) space complexity, ensuring that you minimize pointer overhead during the traversal.
