Feature Request: Add Canvas UI alongside Search and Chat UI

[tim-dim]

Feature Request: Integrating an Canvas UI alongside the existing search and chat interfaces in Danswer. E.g. Open Canvas which is an open-source web application designed to enhance collaborative document writing with AI agents. Inspired by OpenAI's "Canvas," it offers several advantages that could complement the Danswer experience by providing users with a more flexible, document-centric approach to interacting with the platform.
Example: https://open-canvas-lc.vercel.app/

Potential Use Cases:

• Drafting and iterating on documents, reports, or code
• Using RAG for document context across sessions
• Collaborating on text generation in a more structured and organized environment, especially for complex documents that require iteration
