Quick rewrite of dojo readme

[maxkorp]

This could probably be a bit better (and exposes some dx features we could clean up a bit) but this makes the readme stop being flat out wrong

Hi 👋

Following this new Readme, I end up with:

• Run just the demo viewer, and run the agent(s) separately.

Both agent and frontend are running but whenever I start interacting with the chat, I go an error in my browser console:

intercept-console-error.js:50 Error in async callback: Error: Failed to retrieve assistant: fetch failed
    at eval (chunk-OT5NHMEC.mjs:296:19)
    at Generator.next (<anonymous>)
    at fulfilled (chunk-SKC7AJIV.mjs:45:24)

• Use the dojo-everything scripts

./scripts/prep-dojo-everything.js crashes with:

...
[Dojo] pnpm install --no-frozen-lockfile && pnpm build --filter=demo-viewer... exited with code 0

Do you know what can be missing ?

EDIT:

For the "Run just the demo viewer, and run the agent(s) separately."

I was running npm run dev inside of the ag-ui/integrations/langgraph/typescript instead of ag-ui/integrations/langgraph/typescript/examples/src/agents/agentic_chat.

It then asked me to rename .env.example file into .env and fill up the OPENAI_API_KEY and LANGSMITH_API_KEY. I got it working just fine now.

(Use the dojo-everything scripts issue persist though).
