 * bundled plugins need both postgresSchema runtime values and Quality's
 * process-group supervisor. Keep this alias implementation in untyped MJS so
 * tsc stays inside the CLI root while esbuild follows the core source schema
 * and bundles every runtime export without a private @fusion/core dependency.
