feat: add OpenChainBench to Blockchain

[Flotapponnier]

OpenChainBench provides open-source Go harnesses for continuous blockchain infrastructure benchmarking: multi-region RPC provider latency, L1/L2 finality, bridge fees, oracle deviation (Chainlink/Pyth/Redstone), and perp DEX costs across 20+ chains. The harnesses expose Prometheus metrics and use Go's net/http, WebSocket, and JSON-RPC. MIT licensed, CC-BY-4.0 data.

Add OpenChainBench to README Blockchain tools list

📝 Documentation 🕐 Less than 5 minutes

AI Description

• Add OpenChainBench as a Go-based blockchain infrastructure benchmarking harness.
• Document coverage areas (RPC latency, finality, bridge fees, oracle deviation, perp DEX costs).

High-Level Assessment

The current approach (adding a single curated link entry to the existing README section) is the simplest and most consistent with how this repository catalogs tools; no alternative architecture or implementation strategy is warranted.
