feat: initialize crypto_clash_contract with TypeScript, Hardhat, and deployment script

- Added package.json with scripts for compiling, deploying, and testing the contract.
- Created deploy.ts script for deploying the HelloWorld contract and saving the contract address to config.json.
- Configured TypeScript with tsconfig.json for Node.js environment and ES module support.
