[Bug] /clear command doesn't respect defaultMode setting

Bug Description
When using the /clear command with "defaultMode": "plan" configured in .claude/settings.json, the session should reset to plan mode, but it currently preserves the previous permission mode instead.

Expected behavior: /clear should honor the defaultMode: "plan" setting
Actual behavior: Permission mode is preserved after /clear

Configuration:

• ~/.claude/settings.json has "defaultMode": "plan"
• After using /clear, the session remains in execute mode if that was the previous state

Environment Info

• Platform: linux
• Terminal: tmux
• Version: 2.1.9
• Feedback ID: 616e62f6-2343-4ff5-9aad-44aeca95bff9
