Bug: The upgrade to Hardhat v3.1.0 requires adding "type": "module" to package.json because the hardhat.config.ts uses ESM syntax, which will otherwise fail to load.
Severity: CRITICAL | Confidence: High

🔍 Detailed Analysis

The project's hardhat dependency is being upgraded to version 3.1.0. Hardhat 3.0+ is an ESM-first library and requires "type": "module" to be set in the root package.json. The hardhat.config.ts file uses ESM syntax with import and export default statements. Without the "type": "module" declaration, Node.js will default to CommonJS and fail to parse the configuration file, causing any hardhat command to crash. This will break all development and CI workflows that rely on Hardhat.

💡 Suggested Fix

Add the "type": "module" field to the root package.json file. This will ensure Node.js correctly interprets .ts and .js files as ES Modules, which is required for Hardhat v3.0+ to load its configuration.
