chore(recipes): drop NCCL perf checks from gb200-eks-inference

[njhensley]

Summary

Remove the validation.performance block (NCCL NET and NVLS all-reduce bandwidth checks) from the gb200-eks-inference overlay.

Motivation / Context

The NCCL fabric health checks (nccl-all-reduce-bw-net, nccl-all-reduce-bw-nvls) are not needed by default for GB200/EKS inference deployments. Single-node serving hits the WorkerCount < 2 skip path; multi-node serving that actually crosses the fabric can opt in via its own overlay rather than paying for these checks on every inference recipe. The training sibling (gb200-eks-training) keeps them.

Fixes: N/A

Type of Change

• Refactoring (no functional changes)

Component(s) Affected

• Recipe engine / data (pkg/recipe)

Implementation Notes

• Dropped the validation.performance block and its preamble comment from recipes/overlays/gb200-eks-inference.yaml.
• The downstream gb200-eks-ubuntu-inference overlay inherits from this one and had no NCCL block of its own, so it picks up the removal automatically.

Testing

YAML-only change to a single overlay. No Go code touched; the registry/overlay schema still validates.

Risk Assessment

• Low — Isolated data change, easily reverted by restoring the block.

Rollout notes: N/A — users who still want NCCL gating on GB200/EKS inference can add the block back in a private overlay.

Checklist

• I did not skip/disable tests to make CI green
• Changes follow existing patterns in the codebase
• Commits are cryptographically signed (git commit -S)

📝 Walkthrough

Walkthrough

The pull request removes performance validation checks from the GB200 EKS inference recipe configuration. Specifically, it eliminates NCCL fabric bandwidth performance validation entries, including checks for network (EFA) and NVLS/NVL72 paths along with their associated constraint thresholds. This represents a removal of 17 lines from the recipe's validation specification without adding new configuration.
