Move legacy Solidity contracts, Hardhat configuration, and EVM tests to a dedicated legacy/evm/ directory to clean up the workspace and prevent legacy test failures from blocking build and CI gates. Update package.json to make Vitest (Solana tests) the default test suite, and document the EVM status.
