V2.0.1: local Qwen3-VL backend - no silent downloads, single model load

- The endpoint / model field is resolved as: an existing model folder, a
  folder name under models/VLM, or an explicit org/name id (local copy if
  present, otherwise - and only then - a download). A URL or any other value
  (a stray "1" from an old workflow asked Hugging Face for the repo "1") is
  ignored with a log line and a local model is auto-detected. With no local
  model the node stops with an error listing what is in models/VLM.
- The model cache is keyed by the resolved folder, so the image pass and the
  text pass share one copy in VRAM instead of loading the same model twice.
  The Advanced video node's image pass uses the same model field as its text
  pass.
- The system prompt is sent as a system turn; <think> blocks are removed
  from text answers.
