build.ts

/**
 * Builds everything that ships in the npm package:
 *
 * - `dist/ewd.js`, `dist/ewe.js` — the CLIs, CJS bundles with a node shebang.
 * - `dist/index.mjs`, `dist/index.cjs` — the library API (ESM + CJS).
 *
 * All dependencies are inlined, so the published package declares no runtime
 * dependencies. Type declarations (`dist/index.d.ts` + friends) are emitted
 * separately by `tsc -p tsconfig.build.json` in the `build` npm script.
