perf: fast-path token comparison in CodeBlock (#22101)

During streaming, every token change triggers a full JSON.stringify comparison on the code block token object. Add an O(1) fast-path check on token.text and token.raw — the fields that actually change during streaming — before falling back to the expensive JSON.stringify comparison for infrequent structural changes.
