Build me a full Neylon AI web app for proactive customer engagement.

I want a public marketing site, a customer dashboard, and an admin area, all in one app. The product should let a business sign in, create an organization, get a free plan with an API key, set up an embeddable chatbot widget, add website knowledge, view conversations, manage usage and billing, and upgrade plans. The chatbot should support streaming replies, conversation memory, proactive suggestion bubbles, and a setup flow that can crawl a website and generate a basic AI persona.

Make the widget easy to embed with a script tag or React component, and keep it browser safe so it only talks to public HTTP APIs. Include the basic SaaS flow for subscriptions, entitlements, usage metering, and admin reporting. Use the design and structure implied by the repo, and look up current docs online if you need to. Focus on getting the core product working end to end, with clean UI and sensible defaults.
