Problem
Renames and structural edits must touch every real occurrence and nothing else — comments and strings that merely mention a name must be left alone.
Why tree-sitter.zig helps
Queries return only structural matches (identifiers in code positions, never inside unrelated tokens), each with an exact byte range to rewrite.
API
Query with predicates (#eq? on the old name), Node.range, incremental reparse to verify.
Architecture
text
Query old name → ranges → apply text edits → reparse → no stale matches
