Charley Cunningham 2d61357c76 Trim pre-turn context updates during rollback (#15577) ...

## Summary
- trim contiguous developer/contextual-user pre-turn updates when
rollback cuts back to a user turn
- add a focused history regression test for the trim behavior
- update the rollback request-boundary snapshots to show the fixed
non-duplicating context shape
