fix: resolve ESM compatibility issues in CI

- Update Node.js version requirement from >=16 to >=20 in package.json
- Move chalk from devDependencies to dependencies with CommonJS version (^4.1.2)
- Update GitHub workflow to use Node.js 20 instead of 18
- Fix ERR_REQUIRE_ESM error when running evalops CLI in CI environment

This resolves the CI failure where chalk module was trying to be imported
as CommonJS but was ESM-only in newer versions.
