Display plan mode output with tabs instead of sections

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Currently, plan mode displays all content in sequential sections which can be lengthy to scroll through. It would be more user-friendly to organize the plan into tabs that users can navigate between.

Proposed Solution

Organize the plan into tabs that users can navigate between.

Proposed tabs:

• Overview - High-level summary of the approach (shown by default)
• Steps - Detailed implementation steps
• Files to modify - List of files that will be changed
• Verification - How to test/verify the changes

Benefits:

• Reduces visual clutter by showing one section at a time
• Easier to jump directly to the information you need
• Overview tab provides quick scan without scrolling
• Better information architecture for complex plans
