Card: correct the update note (old plugin + new weights)

Mark checkpoint as needing clef-vllm >= 0.2.0

Plugin 0.2.0: version guard so mismatched plugin/weights cannot serve silently

Card: update note for the 2026-10-07 weights + plugin change

8-bit lookup tables: 20.0 -> 17.5 GB, same accuracy and speed; faster server (prompt-sized CUDA graphs, --gdn-backend)

Upload clef-NVFP4 (Clef 27B NVFP4, vLLM plugin + SystemOne server)
