ci(vllm): disable tests-vllm-grpc job (heterogeneous runners)

Both ubuntu-latest and bigger-runner have inconsistent CPU baselines:
some instances support the AVX-512 VNNI/BF16 instructions the prebuilt
vllm 0.14.1+cpu wheel was compiled with, others SIGILL on import of
vllm.model_executor.models.registry. The libnuma packaging fix doesn't
help when the wheel itself can't be loaded.

FROM_SOURCE=true compiles vllm against the actual host CPU and works
everywhere, but takes 30-50 minutes per run — too slow for a smoke
test on every PR.

Comment out the job for now. The test itself is intact and passes
locally; run it via 'make test-extra-backend-vllm' on a host with the
required SIMD baseline. Re-enable when:
  - we have a self-hosted runner label with guaranteed AVX-512 VNNI/BF16, or
  - vllm publishes a CPU wheel with a wider baseline, or
  - we set up a docker layer cache that makes FROM_SOURCE acceptable

The detect-changes vllm output, the test harness changes (tests/
e2e-backends + tools cap), the make target (test-extra-backend-vllm),
the package.sh and the Dockerfile/install.sh plumbing all stay in
place.

+# Adding GGUF Models from HuggingFace to the Gallery
+
+When adding a GGUF model from HuggingFace to the LocalAI model gallery, follow this guide.
+
+## Gallery file
+
+All models are defined in `gallery/index.yaml`. Find the appropriate section (embedding models near other embeddings, chat models near similar chat models) and add a new entry.
+
+## Getting the SHA256
+
+GGUF files on HuggingFace expose their SHA256 via the `x-linked-etag` HTTP header. Fetch it with:
+
+```bash
+curl -sI "https://huggingface.co/<org>/<repo>/resolve/main/<filename>.gguf" | grep -i x-linked-etag
+```
+
+The value (without quotes) is the SHA256 hash. Example:
+
+```bash
+curl -sI "https://huggingface.co/ggml-org/embeddinggemma-300m-qat-q8_0-GGUF/resolve/main/embeddinggemma-300m-qat-Q8_0.gguf" | grep -i x-linked-etag
+# x-linked-etag: "6fa0c02a9c302be6f977521d399b4de3a46310a4f2621ee0063747881b673f67"
+```
+
+**Important**: Pay attention to exact filename casing — HuggingFace filenames are case-sensitive (e.g., `Q8_0` vs `q8_0`). Check the repo's file listing to get the exact name.
+
+## Entry format — Embedding models
+
+Embedding models use `gallery/virtual.yaml` as the base config and set `embeddings: true`:
+
+```yaml
+- name: "model-name"
+  url: github:mudler/LocalAI/gallery/virtual.yaml@master
+  urls:
+    - https://huggingface.co/<original-model-org>/<original-model-name>
+    - https://huggingface.co/<gguf-org>/<gguf-repo-name>
+  description: |
+    Short description of the model, its size, and capabilities.
+  tags:
+    - embeddings
+  overrides:
+    backend: llama-cpp
+    embeddings: true
+    parameters:
+      model: <filename>.gguf
+  files:
+    - filename: <filename>.gguf
+      uri: huggingface://<gguf-org>/<gguf-repo-name>/<filename>.gguf
+      sha256: <sha256-hash>
+```
+
+## Entry format — Chat/LLM models
+
+Chat models typically reference a template config (e.g., `gallery/gemma.yaml`, `gallery/chatml.yaml`) that defines the prompt format. Use YAML anchors (`&name` / `*name`) if adding multiple quantization variants of the same model:
+
+```yaml
+- &model-anchor
+  url: "github:mudler/LocalAI/gallery/<template>.yaml@master"
+  name: "model-name"
+  icon: https://example.com/icon.png
+  license: <license>
+  urls:
+    - https://huggingface.co/<org>/<model>
+    - https://huggingface.co/<gguf-org>/<gguf-repo>
+  description: |
+    Model description.
+  tags:
+    - llm
+    - gguf
+    - gpu
+    - cpu
+  overrides:
+    parameters:
+      model: <filename>-Q4_K_M.gguf
+  files:
+    - filename: <filename>-Q4_K_M.gguf
+      sha256: <sha256>
+      uri: huggingface://<gguf-org>/<gguf-repo>/<filename>-Q4_K_M.gguf
+```
+
+To add a variant (e.g., different quantization), use YAML merge:
+
+```yaml
+- !!merge <<: *model-anchor
+  name: "model-name-q8"
+  overrides:
+    parameters:
+      model: <filename>-Q8_0.gguf
+  files:
+    - filename: <filename>-Q8_0.gguf
+      sha256: <sha256>
+      uri: huggingface://<gguf-org>/<gguf-repo>/<filename>-Q8_0.gguf
+```
+
+## Available template configs
+
+Look at existing `.yaml` files in `gallery/` to find the right prompt template for your model architecture:
+
+- `gemma.yaml` — Gemma-family models (gemma, embeddinggemma, etc.)
+- `chatml.yaml` — ChatML format (many Mistral/OpenHermes models)
+- `deepseek.yaml` — DeepSeek models
+- `virtual.yaml` — Minimal base (good for embedding models that don't need chat templates)
+
+## Checklist
+
+1. **Find the GGUF file** on HuggingFace — note exact filename (case-sensitive)
+2. **Get the SHA256** using the `curl -sI` + `x-linked-etag` method above
+3. **Choose the right template** config from `gallery/` based on model architecture
+4. **Add the entry** to `gallery/index.yaml` near similar models
+5. **Set `embeddings: true`** if it's an embedding model
+6. **Include both URLs** — the original model page and the GGUF repo
+7. **Write a description** — mention model size, capabilities, and quantization type

 - The user may say they want to build AMD or ROCM instead of hipblas, or Intel instead of SYCL or NVIDIA insted of l4t or cublas. Ask for confirmation if there is ambiguity.
 - Sometimes the user may need extra parameters to be added to `docker build` (e.g. `--platform` for cross-platform builds or `--progress` to view the full logs), in which case you can generate the `docker build` command directly.

+## End-to-end gRPC tests that exercise a built backend container image.
+##
+## The test suite in tests/e2e-backends is backend-agnostic. You drive it via env
+## vars (see tests/e2e-backends/backend_test.go for the full list) and the
+## capability-driven harness picks which gRPC RPCs to exercise:
+##
+##   BACKEND_IMAGE            Required. Docker image to test, e.g. local-ai-backend:llama-cpp.
+##   BACKEND_TEST_MODEL_URL   URL of a model file to download and load.
+##   BACKEND_TEST_MODEL_FILE  Path to an already-downloaded model (skips download).
+##   BACKEND_TEST_MODEL_NAME  HuggingFace repo id (e.g. Qwen/Qwen2.5-0.5B-Instruct).
+##                            Use this instead of MODEL_URL for backends that
+##                            resolve HF model ids natively (vllm, vllm-omni).
+##   BACKEND_TEST_CAPS        Comma-separated capabilities, default "health,load,predict,stream".
+##                            Adds "tools" to exercise ChatDelta tool call extraction.
+##   BACKEND_TEST_PROMPT      Override the prompt used in predict/stream specs.
+##   BACKEND_TEST_OPTIONS     Comma-separated Options[] entries forwarded to LoadModel,
+##                            e.g. "tool_parser:hermes,reasoning_parser:qwen3".
+##
+## Direct usage (image already built, no docker-build-* dependency):

+##       BACKEND_TEST_MODEL_URL=https://.../model.gguf
