Key Features

Chat UI Iframe Embedding: The CSP (Content Security Policy) configuration has been updated to allow the chat UI to be embedded as an iframe, enabling developers to integrate Sim's chat interface directly into external applications and websites.

Knowledge Base Upsert Operation: A new upsert document operation has been added to the knowledge module, allowing developers to create or update documents in a single API call rather than checking existence first.

Resizable Chat/Resource Panel: The home interface now features a resizable divider between the chat and resource panels, giving users more control over their workspace layout.

Request IDs in Mothership: Request tracking has been enhanced with request ID support in the mothership infrastructure, improving observability and debugging capabilities.
