per_turn_effort_changed system events are skipped

System events marking a per-turn effort change are now skipped in one event loop, like preempted-turn events

What

One loop that works through the events of a conversation now skips system messages of type per_turn_effort_changed. It handles them the same way it already handled turn_preempted. The old version of this check appears to have had a typo that tested the wrong value, and the new version tests the message itself.

Why

Effort-change events are no longer handled by that loop, and the skip check now looks at the message it is meant to.
