Remove 'prometheus' from PLAN_AGENT_NAMES so isPlanAgent() no longer matches prometheus. The only remaining connection is model inheritance via buildPlanDemoteConfig() in plan-model-inheritance.ts. - Remove 'prometheus' from PLAN_AGENT_NAMES array - Update self-delegation error message to say 'plan agent' not 'prometheus' - Update tests: prometheus is no longer treated as a plan agent - Update task permission: only plan agents get task tool, not prometheus
