Hard-coded 'scout' references reached the model even when the scout agent was disabled via task.disabledAgents or absent from the session spawn list. Gate every such reference on scout actually being spawnable: the task tool description, the delegation gates, the plan-mode and workflowz notices, the glob/grep/ast-grep guidance, and the task specialization advisory. Prompt shape is otherwise unchanged; only erroneous references to the unavailable subagent are dropped. Closes #7313
