Rename UI heading to Hybrid Vision RAG PDF

Full VLM analysis for every image + accurate ready/trained timing

Force embedding model to CPU (avoid ZeroGPU CUDA init outside @spaces.GPU)

Show masked key fingerprint in UI; add Go-to-Chat button that switches tabs on completion

Force Docling accelerator to CPU (avoid ZeroGPU CUDA init outside @spaces.GPU)

Move @spaces.GPU to picklable stub; run process_pdf on CPU to avoid ZeroGPU pickle crash

Decorate process_pdf with @spaces.GPU (ZeroGPU Space requires a GPU fn)

Monkeypatch gradio_client json_schema_to_python_type to handle bool schemas (api_info crash)

Use ssr_mode=False (correct kwarg name) to disable Gradio 5 SSR

Set sdk_version 5.20.0 for ssr kwarg; drop gradio from requirements to avoid SDK pin conflict

Pin gradio>=5.20 so launch(ssr=False) kwarg exists

Disable Gradio 5 SSR (ssr=False) to fix HF Space render crash

Upgrade to Gradio 5 to fix api_info bool TypeError; set Chatbot type=messages

Initial commit: Hybrid Vision RAG PDF Processor for HF Space
