…utputs The token counting logic for tool schemas assumes enum values are always strings and passes them directly to tiktoken.encode(). When a Pydantic model uses IntEnum or other non-string enum types, this raises a TypeError because tiktoken only accepts strings. Wrap enum values with str() before encoding, matching the pattern already used for other JSON Schema fields like 'type'. Fixes microsoft#7201
