* fix(agentenv): bind solve results to the named verifier
* fix(agentenv): retain a planned solve pass through selected-verifier binding
Cleanup and cancellation tests plan a completed pass with no criterion
rows. An empty selected-verifier result list is unscored, so those
reports lost outcome passed even though sandbox retention and the
cancellation cause were unchanged. Record one selected result for a
planned pass or miss so the bound outcome stays the planned one.
