+Streaming guarantees (ChatGPT-style, no buffering):

+- Tokens are forwarded via `controller.enqueue` the moment they arrive from the
+  LLM; disconnects are detected (`req.signal`, guarded `enqueue`,
+  stream `cancel()`) and propagated upstream via an `AbortController` passed as
+  `opts.signal`, so the model stops generating when the tab closes.
+- `Bun.serve` runs with `idleTimeout: 0` — the default 10 s would kill slow
+  streams (cold model load, thinking pauses) mid-generation.
+- Responses carry `X-Accel-Buffering: no` and the NixOS nginx vhost sets
+  `proxy_buffering off`, otherwise the proxy would buffer the whole reply.
