[Bug] ExitPlanMode skips approval dialog and auto-accepts plan

Bug Description
When Claude calls ExitPlanMode, the plan is automatically accepted without showing the 4-option approval dialog. This happens consistently in the same conversation context.

Expected behavior:
The user should see the approval UI with these four options:

1. Yes, clear context and auto-accept edits (default)
2. Yes, and manually approve edits
3. Yes, auto-accept edits
4. Yes, manually approve edits

Actual behavior:
The approval dialog never appears. The plan is silently auto-approved and Claude immediately proceeds to implementation.

Reproduction steps:

1. Ask Claude to implement something that triggers plan mode
2. Claude enters plan mode, explores codebase, writes the plan
3. Claude calls ExitPlanMode
4. No approval UI appears — plan is auto-accepted
5. Claude begins implementation without user choosing an option

Impact:
Users lose the ability to choose between context clearing, auto-accept vs manual approval, or to reject the plan entirely.

Environment:

• Claude Code CLI
• macOS
