/**
 * A piece table is a data structure that allows for efficient insertion and deletion of text.
 * It is a tree of pieces, where each piece is a segment of text that is either original or added.
 * The tree is a treap (a binary search tree that also keeps each node's random priority in heap
 * order, which keeps the tree balanced without an explicit rebalancing pass). Each edit reshapes
 * only the nodes along one root-to-leaf path via split and merge in O(log P), instead of
 * rebuilding all P pieces.
 * Inspired by https://code.visualstudio.com/blogs/2018/03/23/text-buffer-reimplementation
