Extend a running experiment’s collection window

Use when: caller wants to push out an experiment’s auto-completion deadline because the sample size or signal isn’t strong enough yet

Extends min_sample_size / duration_days / max_requests on a running or paused experiment. Unlike the general PATCH which locks statistical fields once running, this route exists specifically for extension — new values must be ≥ current (shrinking would invalidate the statistical framework). At least one field must be provided. This is the path Einstein’s Interpreter uses for the extend_run action.
