VSCode Extension: Plan content not visible before approval prompt in ExitPlanMode

Bug Description

When using plan mode in the Claude Code VSCode extension, calling ExitPlanMode triggers an approval prompt before the user can see the plan content. This leaves users unable to make an informed decision about whether to approve the plan.

Environment

• Tool: Claude Code VSCode Extension
• Mode: Plan mode active
• OS: Linux (Ubuntu)

Steps to Reproduce

1. User triggers plan mode (e.g., via a planning task)
2. Claude writes the plan to the designated plan file using the Write tool
3. Claude calls ExitPlanMode to request user approval
4. Bug: User sees the approval prompt but the plan file content has not been displayed/rendered in the UI

Expected Behavior

The plan content should be visible to the user before they are asked to approve or reject it. Either:

• The plan content should be displayed inline before the approval prompt
• Or the approval dialog should include/show the plan content

Actual Behavior

The approval prompt appears immediately after ExitPlanMode is called, but the plan content is not shown. The user has no way to review what they are being asked to approve.

User Impact

Users must reject the approval, manually read the plan file, and then re-trigger the approval flow — or blindly accept without knowing the plan contents.

Additional Context

This was observed during a planning session where the plan file was written to /home/user/.claude/plans/<plan-name>.md. The Write tool succeeded, but the content was never surfaced to the user before the approval prompt appeared.
