Minor cleanups noticed while implementing #33.
w3c/traceparent.LoadFromEnv has no production callers now that config_span.go reads the env carrier through envcar (otelcli/propagation.go:envCarrierTraceparent). Only its own unit test calls it. Decide: keep as a documented w3c/traceparent utility, or deprecate/remove.otelcli/exec.go: strings.Replace(arg, "{{traceparent}}", ..., -1) → strings.ReplaceAll(...) (staticcheck QF1004). Trivial, pre-existing.
Low priority; bundle into a future propagation PR (e.g. #34).
