fix(structuredClone) - remove warning

[gabrielseco]

I have users telling me this warning adds noise as they think they could have an error

---

Note

Low Risk
Logging-only change in a clone helper; clone and fallback behavior are unchanged.

Overview
Removes the console.warn when structuredClone throws in safeDeepClone, so the existing JSON parse/stringify fallback runs silently instead of looking like an application error to users.

Behavior is unchanged: still tries structuredClone first, then falls back on failure.
