Install and configure use of the NCCL version recommended by vLLM via the [vllm-nccl](https://github.com/vllm-project/vllm-nccl) package. The install is a little wonky... but this set of changes should work. Signed-off-by: Travis Johnson <tsjohnso@us.ibm.com>

…ject#26) With eagle3 speculative decoding (num_speculative_tokens=4), the target model verification pass has batch size 5 (1 original + 4 speculative tokens). The skinny GEMM kernels only supported N<=4, causing fallback to a slow dequant + F.linear path that regressed decode throughput by 28% on Qwen3-30B-A3B-AWQ with eagle3. Add case 5 to all skinny GEMM kernel switch statements (fp16, int4, int4_g, int8) and raise SKINNY_GEMM_MAX_N from 4 to 5 so the fast HIP kernel path is used during speculative verification. Benchmark (Strix Halo, Qwen3-30B-A3B-AWQ-4bit, eagle3 specdec): Before fix: 81.3 tokens/s decode After fix: 115.7 tokens/s decode (+42%) Baseline: 113.3 tokens/s decode (pre-regression)
