[Feature Request] Add GUI text input interface to VS Code extension

Feature Request

The current VS Code extension only supports terminal-based input. It would be great to have an optional GUI text input interface (chat panel) as well.

Why?

• Easier to compose multi-line messages
• Better message history visibility
• Similar to other AI extensions (GitHub Copilot Chat, etc.)
• More intuitive for many users

Proposal

Add an optional chat panel with:

• Text input box
• Message history display
• Toggle between terminal/GUI modes

This would complement the existing terminal integration while providing a more accessible option for users who prefer GUI interactions.

Thank you for considering this feature\!
