Foundry Forge

Compiles, tests, fuzzes, debugs, and deploys Solidity smart contracts using Forge — the core build and test tool in the Foundry suite. Covers writing and running Forge tests, cheatcodes (vm.prank, vm.warp, vm.expectRevert, and the full vm.* API), fuzz and invariant testing, forge script deployments and multi-chain broadcasts, contract verification on Etherscan, gas snapshots, forge coverage, and all forge CLI subcommands. Also covers forge-std imports: Test.sol, Script.sol, StdAssertions, StdCheats, StdStorage. Activates when Solidity test code or a forge script is present, or when any Forge or forge-std topic is mentioned.
