Chat UI Iframe Embedding: The chat interface can now be embedded in iframes through updated Content Security Policy (CSP) headers, enabling developers to integrate Sim chat directly into third-party applications and websites.

Knowledge API Enhancement: A new upsert document operation has been added to the knowledge module, allowing developers to insert or update documents in a single API call rather than using separate create/update operations.
