Minor adjustments

@DavertMik Also add:

1. Prevents Explorbot from planning or passing entity-specific actions when the action is not confirmed for that exact UI entity type
2. Reduces long no-progress runs by failing earlier when repeated attempts or execution errors do not change the browser state
