ExitPlanMode incorrectly returns false user approval

Bug Description
ExitPlanMode Bug Report

Issue: ExitPlanMode tool returns false approval without user interaction

Behavior:

1. Call ExitPlanMode with a plan
2. Tool immediately returns "User has approved your plan"
3. User never sees or approves the plan
4. Assistant remains in plan mode (system reminders confirm this)

Impact: Cannot properly exit plan mode or get user approval for plans

Environment:

• Claude Code CLI
• Custom hooks installed (verified not interfering - only logging tool

usage)

Evidence:

• ExitPlanMode called twice, both times returned false approval
• Hooks logs show tool processed normally
• No hook code modifies tool responses
• Plan mode persists despite "approval" message

Expected: ExitPlanMode should prompt user for approval before returning

Environment Info

• Platform: darwin
• Terminal: Apple_Terminal
• Version: 1.0.67
