The shipped workflow is Hugging Face Jobs (examples/annotations/run_hf_
job.py): it serves the model with vLLM in the vllm/vllm-openai image and
the pipeline talks to it over the OpenAI-compatible API. The in-process
vllm / transformers local backends added surface (and the vllm
one pinned an old torch) without being part of that path, so they're
removed for now.
* vlm_client.make_vlm_client: keep only backend='openai' (+ 'stub'
rejected with the usual guidance). Requesting 'vllm'/'transformers'
now raises a clear 'not supported for now — use the HF Jobs flow'
error. Removed _make_vllm_client and _make_transformers_client.
* config: backend docstring updated (openai-only); default model_id
bumped to Qwen/Qwen3.6-27B to match run_hf_job.
* docs/annotation_pipeline.mdx: remove the '## Running locally'
section; the launcher description now says one vLLM server per GPU
over the OpenAI API, and the 'One Qwen-VL pass' note drops the
'vLLM/transformers fallback' wording.
Tests are unaffected (they construct StubVlmClient directly; nothing
referenced the removed backends).
