When vLLM runs with Ray Prometheus `vllm:request_success{finished_reason=...}`
only ever increments the repetition bucket regardless of the request's actual finish
reason; stop, length, abort, and error stay at zero. Root cause was `labels()` mutated
the wrapped Ray metric's default tags in place and returned self, so every `.labels(...)`
call on a given wrapper returned the same object.
