Replace the GPTQ W4A16 30B-A3B coder with Qwen2.5-Coder-14B-Instruct at
fp16 on TP=2.
The V100 has FP16 tensor cores and no INT4 ones, so the 4-bit path paid a
dequantisation pass on the SM. Profiling showed SM at 98% with the memory
controller at 19%, and the batch-1 step cost matched a full-model read.
Same harness, 16 streams: ITL 71.5 -> 39.7 ms, 215 -> 287 tok/s.
The deployment keeps the candle-vllm name and the app: candle-vllm label,
so coder-service.yaml and every client keep working unchanged.
