Subject: [PATCH] docs: add HSTU (Generative Recommenders) tutorial page

Add Popular_Models_Guide/HSTU/README.md introducing HSTU/GRs and pointing
to the recsys-examples model/training/export/inference guides and the
PyTorch backend AOT Inductor (torch_aoti) docs. Add a Generative
Recommenders row to the top-level tutorials table.

+# HSTU Generative Recommenders on Triton
+
+[Hierarchical Sequential Transduction Units (HSTU)](https://arxiv.org/abs/2402.17152)
+power **Generative Recommenders (GRs)**: recommendation workloads reformulated as
+generative modeling over high-cardinality, non-stationary event streams. HSTU
+supports both retrieval and ranking style tasks.
+
+Triton Inference Server can serve HSTU models through the
+[PyTorch backend](https://github.com/triton-inference-server/pytorch_backend)
+using ahead-of-time (AOT) Inductor packages (`platform: "torch_aoti"`). Training,
+export, KV-cache runtime, and end-to-end examples live in NVIDIA's
+[recsys-examples](https://github.com/NVIDIA/recsys-examples) repository rather
+than in this tutorials tree.
+
+## Where to go next
+
+| Resource | Description |
+| -------- | ----------- |
+| [HSTU overview](https://github.com/NVIDIA/recsys-examples/blob/main/examples/hstu/README.md) | Architecture, training, and inference entry points |
+| [HSTU inference](https://github.com/NVIDIA/recsys-examples/blob/main/examples/hstu/inference/README.md) | Inference features, KV-cache, AOTInductor export, and KuaiRand examples |
+| [PyTorch AOTI on Triton](https://github.com/triton-inference-server/pytorch_backend#aot-inductor-support-beta) | `torch_aoti` model repository layout and configuration |
+
+> [!NOTE]
+> Use the recsys-examples guides for building, exporting, and validating HSTU
+> models. This page only points Triton users at that workflow and the Torch AOTI
+> serving path.

 # Triton Tutorials
 
 For users experiencing the "Tensor in" & "Tensor out" approach to Deep Learning Inference, getting started with Triton can lead to many questions. The goal of this repository is to familiarize users with Triton's features and provide guides and examples to ease migration. For a feature by feature explanation, refer to the [Triton Inference Server documentation](https://docs.nvidia.com/deeplearning/triton-inference-server/user-guide/docs/index.html).
