TreeReuser class

AST subtree reuse utility

Refers to tree-sitter's tree reuse strategy: After an edit occurs, the top-level child nodes of the old AST are classified into three categories based on TextEdit:

1. Prefix nodes: sourceRange is entirely before the edit start -> retained directly
2. Dirty nodes: sourceRange overlaps with the edit region -> must be re-parsed
3. Suffix nodes: sourceRange is entirely after the edit end -> reused after offset shift
