⚖️ The AVL Balancer

Every insert checks itself on the way back up. The moment a subtree tips more than one level lopsided, the tree physically rotates — nodes swap levels — until every branch is balanced again.

⚖️ BalancerAfter every insert, I check the balance factor of every ancestor on the path back to the root. More than 1 off, and I act immediately — never later.
🔄 RotationI never lose a single node. I just swap who's the parent and who's the child, locally, in O(1) — the whole rest of the tree stays untouched.
Pick a level above to begin.
