Implement JayToken (standard ERC-20 with custom errors) and JayEscrow (single-use buyer/seller escrow via approve + transferFrom) with their deploy scripts. Remove the unused Counter.s.sol scaffold so the folder builds. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Implements the week-4 assignment in
Tokens-wk4/Erc20-token/Assignments:src/JayToken.sol— a standard ERC-20 (name, symbol, decimals, transfer, approve, transferFrom) with custom errors and zero-address checks. Mints the initial supply to the deployer.src/JayEscrow.sol— a buyer locks tokens for a seller until a deadline. The buyer can release the funds to the seller, or refund themselves once the deadline passes. Each escrow has its own ID, so multiple users can use the same contract.Deployment scripts for both contracts.
Also removed the leftover
Counter.s.sol, which imported aCounter.solthat doesn’t exist and prevented the folder from building.Ran
forge fmtandforge build— both clean.
