/**
 * Runnable house-pattern generators (WP-43). `npm run gen <name>` or the `gen:*` scripts.
 * These emit the boilerplate the skills used to describe by hand; each generated unit ships
 * with its co-located spec so the "domain/pure logic must have a spec" rule holds by default.
 *
 * Generators here are the pure-TS patterns (no Angular-template escaping): value objects and
 * form/wizard state machines. The UI-component and bff-endpoint patterns stay skill-driven —
 * they span the template `{{ }}` syntax / the C# backend + `gen:api` regen, where a generator
 * adds little over the recipe. `context` (WP-44) mechanises the `new-context` skill's manual
 * multi-file edit: folders + tsconfig alias + boundary entry + lazy route.
 *
 * Positional args skip the prompts, e.g. `npx plop value-object registratie KvkNummer`.
