Agent(type) deny and Agent(x,y) allowed-types rules were not enforced for named subagent spawns until 2.1.186

What this changes for operators

• 2.1.186 fixed Agent(type) deny rules and Agent(x,y) allowed-types restrictions not being enforced for named subagent spawns. An operator who wrote those rules when the argument-aware grammar was announced was unprotected by them until this fix.
• Upgrade past 2.1.186, then write an Agent(type) deny for a subagent you expect blocked and confirm a named spawn is actually refused, not silently allowed.
