/**
 * Recipe transpile step — runs in the trusted parent process.
 *
 * esbuild compiles and bundles a `.recipe.ts` into a single self-contained
 * CommonJS string. Transpiling is **not** executing — esbuild reads and
 * rewrites the source, it never runs the recipe. The bundle is then handed
 * to the confined child (`./recipe-runner.cjs`), which runs it as plain JS
 * with no TypeScript toolchain — which is what lets the child run under
 * Node's permission model (no worker threads needed). See
 * docs/recipe-sandbox.md.
