[BUG] Desktop - Planning Responses (Accept/Accept & Auto)

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

In Plan Mode, clicking the "Accept" button immediately begins implementation (writing files, running commands) — behaving identically to "Accept and Implement." The two buttons produce the same outcome, making it impossible to approve/save a plan without triggering code execution.

This occurred 4-5 times in a single session. Each time the user clicked Accept intending only to acknowledge the plan, Claude began creating directories, writing files, and running PowerShell commands before the user could intervene.

What Should Happen?

Clicking "Accept" should save/acknowledge the plan and return to normal conversation mode without executing anything. Implementation should only begin if the user explicitly clicks "Accept and Implement" or gives a follow-up instruction to start building.

Error Messages/Logs

No error messages — the bug is silent. Claude proceeds into implementation without any warning or confirmation that execution is starting.

Session ID (from AppData path): 090faba7-6b1d-4ac1-bc1c-8795e82abcf9

Steps to Reproduce

1. Start a multi-turn Claude Code session (desktop app, Windows)
2. Ask Claude to create a plan for a task (e.g., "create a plan for X")
3. Claude enters Plan Mode and presents the plan, then calls ExitPlanMode
4. The plan approval UI appears with two buttons: "Accept" and "Accept and Implement"
5. Click "Accept" (not "Accept and Implement")
6. Observe: Claude immediately begins implementation — creating files, running commands — without waiting for further instruction
