[Feature Request] Configure Edit Display Mode When IDE is Connected

## Current Behavior
When IDE integration is enabled via /ide, Claude Code automatically displays all file edits as diffs inside the connected editor (e.g., VS Code). This requires switching away from the terminal to review and
accept/reject changes.

## Desired Behavior
Add a configuration option (via /config) to control how edits are displayed when an IDE is connected:

• Option 1 (current): Show diffs in the connected IDE editor
• Option 2 (requested): Show diffs inline in the terminal (similar to when no IDE is connected), while still maintaining the IDE connection for other features

Use Case

I want to keep my workflow entirely in the terminal and review/accept diffs without context switching, BUT I still want to benefit from IDE integration features such as:

• Real-time diagnostics
• Ability to send file from editor
• etc

Proposed Solution

Add a new setting in /config: Edit Display Mode: [terminal | ide | auto] or similar, allowing users to keep IDE connected for diagnostics while controlling where edit diffs are displayed.
