docs: polish pass — fix stale names, duplicates, branding, and README

- Normalize 'VLLM' to 'vLLM' in prose across 6 docs (32 occurrences; wikilink
  targets untouched)
- Remove duplicated Environment Variables block in 27B Dankclaw doc
- Update stale model refs Qwen3-30B-A3B -> Qwen3.6-35B-A3B in example commands
- Fix VLLM Index: -- separators to em-dashes; correct model names on links
- README: document active services (ROCmFPX llama-server on Dankclaw, vLLM
  AWQ on Dankserver), replace broken [[docs/README.md]] link with docs/index.md

 ## Overview
 
-Dankserver uses NVIDIA GPU with system RAM for hybrid processing. VLLM splits model weights onto GPU and moves KV cache between GPU VRAM and system RAM. This allows larger models to run on GPUs with limited VRAM.

 ## Architecture
 
 ### Model Weights
 
-Model weights stay on GPU. VLLM loads the entire model into GPU memory. You cannot offload model weights to CPU. The GPU must hold all model parameters.
