Intro to Hardhat / Foundry — Project shape

StructureKeep contracts in contracts/, tests in test/, scripts in scripts/. Add a README with install, test, and deploy commands.

TasksHardhat tasks/plugins extend commands (compile, test, run scripts, verify). Foundry offers forge/cast for similar flows.

SpeedPrefer lightweight tests; cache builds. Foundry’s forge is especially fast for Solidity unit tests.
