The rule that runs delete_instance_message safely

delete_instance_message is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect ProAgentStore, apply this rule, and every delete_instance_message call is checked against it from then on.
