[FEATURE] Write publishable benchmark results document

[chatton]

Problem to solve

After running benchmarks on dedicated hardware, we need a publishable document consolidating the results across all workload scenarios.

Proposed solution or feature

Write a benchmark document that includes:

• hardware specs, software versions, configuration
• per-workload results table (MGas/s, TPS, block intervals, ev-node overhead)
• latency breakdown from trace spans
• identified bottlenecks and optimization opportunities

Alternatives considered

N/A

Additional context

Part of #2288. Depends on throughput experiments completing on dedicated hardware.

A sample of what this could look like based off WIP data

  ## ev-node Benchmark Results

  | Metric              | ERC20      | GasBurner  |
  |---------------------|------------|------------|
  | MGas/s              | 55.14      | 458.00     |
  | TPS                 | 1414       | 153        |
  | s/Ggas              | —          | 2.18       |
  | Block interval p50  | 102ms      | 108ms      |
  | Block interval p99  | 245ms      | 312ms      |
  | Gas/block avg       | 12.3M      | 2.6G       |
  | Non-empty ratio     | 19.8%      | 100%       |
  | ev-node overhead    | 1.6%       | 2.1%       |

  ### Latency Breakdown (avg μs)
  | Span                        | ERC20  | GasBurner |

  | Executor.ExecuteTxs         | 114000 | 83000     |
  | Engine.GetPayload           | 1200   | 1100      |
  | Engine.NewPayload           | 2400   | 2200      |
  | DA.Submit                   | 50     | 48        |
