Subject: [PATCH] fix: Convert benchmark test files to ES module syntax

- Convert gas-usage.test.js from CommonJS require() to ES module import
- Convert execution-time.test.js from CommonJS require() to ES module import
- Convert throughput.test.js from CommonJS require() to ES module import
- Required because contracts/package.json has "type": "module"
