fix: replace retired Qwen2.5 model in tutorial 30

Tutorial 30 calls `Qwen/Qwen2.5-7B-Instruct` through `provider="together"`,
which routes to Together's `Qwen2.5-7B-Instruct-Turbo`. Together retired
that model from serverless, so the HF provider mapping now reports
`status=error` and the model is gone from the router's model list. The
nightly log already shows the health-check warning for it.

Swap in `Qwen/Qwen3.5-9B` and disable thinking. Qwen3.5 is a hybrid
thinking model, and left on it spends ~8x the completion tokens (1292 vs
165 on this tutorial's prompt) and prepends a 4 KB reasoning trace, which
would make the tutorial's sample response unrepresentative.

Note this does not by itself make the nightly green: that run failed with
`402 Payment Required` — "You have depleted your monthly included
credits" — which no code change can fix.
