What is Spiral Matrix?
Given an m by n matrix, return all elements in spiral order. You maintain four boundaries (top, bottom, left, right) and peel one layer at a time, moving right, down, left, then up, shrinking the boundaries after each direction. This problem teaches careful boundary management and is a good test of whether you can translate a visual pattern into clean code.
