docs(DeepSeek-V4): verify H200 Pro max-throughput recipe

[yhyang201]

Summary

• Update H200 Pro (1.6T) max-throughput recipe parameters to match verified 2-node (16 GPU) deployment
• DISPATCH_TOKENS: 256 → 128
• --max-running-requests: 256 → 64
• --mem-fraction-static: 0.82 → 0.875
• Remove --cuda-graph-max-bs 128 (not needed for H200 big)
• Mark h200|big|max-throughput as verified

Test plan

• Verified on 2-node H200 cluster (Ion-5 + Ion-6, 16 GPU total)
• Existing H200 small recipes unaffected (separate code path)
• Other platform recipes unaffected

Code Review

This pull request adds the 'h200|big|max-throughput' configuration to the DeepSeek-V4 deployment documentation, updating environment variables and CLI flags for H200 hardware. Specifically, it adjusts memory fraction and request limits for the 'big' variant. A review comment suggests consolidating the conditional logic for H200-specific overrides to enhance code readability and maintainability.

The logic for adding flags in the max-throughput recipe is slightly fragmented across multiple if blocks. While functional, consolidating the hardware === "h200" && isBig check would improve readability and maintainability, especially as more hardware-specific overrides are added.

      if (hardware === "h200" && isBig) {
        flags.push("  --mem-fraction-static 0.875");
        flags.push("  --max-running-requests 64");
      } else {
        if (isBig) flags.push("  --mem-fraction-static 0.82");
        if (hardware === "h200") {
          flags.push("  --cuda-graph-max-bs 128");
          flags.push("  --max-running-requests 256");
        } else if (isBig && hardware === "b200") {
          flags.push("  --cuda-graph-max-bs 64");
          flags.push("  --max-running-requests 256");
        } else if (isBig && hardware === "gb300") {
          flags.push("  --cuda-graph-max-bs 128");
          flags.push("  --max-running-requests 256");
        }
      }
