[Bug] Unexpected high token consumption with multi-agent Opus orchestrator spawning Sonnet agents

Bug Description

• Running an Opus orchestrator
• It's spinning up a "general-purpose" agent, model undefined
• I have barred it from spawning Opus agents in settings.json. Sonnet and Haiku only
• Nevertheless, the subagent managed to use up 150K tokens, not get the job finished, and use up 70% off the 5-hour limit (on 5x Max plan)

Environment Info

• Platform: darwin
• Terminal: vscode
• Version: 2.1.121
• Feedback ID: 56a9197f-5b2d-4999-a52e-f51ea757263f
