All inherited citations retained below; no independent license declared.
Idea: During the existing bottom-up maximum-position sweep, accumulate each
parent's descendant count in the zero-initialized size array. A subtree has
one more state than this count, so preorder needs no separate initialization
or bottom-up link traversal. The sweep still stays lazy for full-range queries.
Purpose: Remove a repeated irregular traversal and the size initialization pass.

reused the suffix engine and block-first witness probe with its maximum-position
shortcut. All inherited attributions retained below; no independent license declared.
Idea: Initialize subtree sizes sequentially for states 2..s_sz. The root is
not counted in the length histogram, and ord_ contains exactly these nonroot
states: skip the temporary overwritten root insertion and remove root/zero-
parent guards from the metadata sweeps, retaining their full original bounds.
Purpose: Reduce random initialization stores and repeated setup guards.
