Suggestion: Add AI-powered assistant widget to llm-d documentation site

Purpose

As documentation is a key part of onboarding for any OSS project, I’d like to suggest adding a web-integrated AI assistant to the llm-d documentation site.

Many modern open-source projects (like vLLM) have introduced AI widgets that help users get contextual answers directly within the docs, significantly improving discoverability and usability. Here's an example from vLLM’s site:

💡This could help new adopters of llm-d quickly find answers to setup, configuration, or usage questions without having to search or open multiple issues.
