Minor Changes

• 19cd137: feat: emit minimal $feature_flag_called events when the server enables the minimal_flag_called_events gate and the evaluated flag has no linked experiment. Minimal events keep a strict allowlist of flag-evaluation properties and strip everything else (context properties, $feature/<key>, payloads, system metadata). The gate is read from the top-level minimalFlagCalledEvents field of the v2 /flags response and the top-level minimal_flag_called_events key of the local evaluation definitions payload; when either signal is missing, the full event is sent unchanged.
