Add a "tuning ds4 for performance" note to the global ds4 Settings section and a
condensed inline note to the per-model ds4 streaming section on the Models page:
NVMe/SSD placement (≈10× prefill), capping the expert cache by count, sizing the
VRAM reserve, DS4_CUDA_WEIGHT_ARENA_CHUNK_MB=512, avoiding DS4_CUDA_WEIGHT_CACHE,
and that decode of a model larger than VRAM is streaming-bound (smaller quant is
the real fix). Distilled from measured tuning on the 154GB DeepSeek-V4 MoE.
