/**
* Generates the Sim CLI's view of the public v2 API from the Zod route
* contracts, so the terminal and the server cannot describe the same endpoint
* differently.
*
* The contracts under `apps/sim/lib/api/contracts/v2/**` are the single source
* of truth: the routes validate against them, so a shape that disagrees with a
* contract is a shape the server would reject. Everything downstream is derived
* rather than restated.
*
* The CLI cannot import the contracts directly — `packages/*` must never depend
* on `apps/*` (scripts/check-monorepo-boundaries.ts). This script bridges that
* at build time instead: it reads the contracts here and emits a file of plain
* type declarations with no imports at all, so nothing about the package
* boundary changes.
*
* Deliberately NOT generated: the OpenAPI documents under `apps/docs`. They
* carry hand-written descriptions, examples, and error responses that Zod
* schemas do not encode. `scripts/check-openapi-specs.ts` reconciles those
* against the same contracts instead, field by field, so the prose survives
* while drift still fails CI.
*
* Usage:
* bun run scripts/generate-v2-cli-api.ts # write the generated file
* bun run scripts/generate-v2-cli-api.ts --check # fail if it is stale
