apps/api boots a NestJS application with: Zod-validated environment
configuration (schema in @dorfteich/shared, fails fast listing every
invalid variable), structured pino request logging via nestjs-pino
(pretty in development, JSON otherwise, auth headers redacted), a
global exception filter producing the uniform ApiErrorBody shape, and
GET /api/v1/healthz. Vitest runs Nest through SWC for decorator
metadata; supertest covers healthz and the 404 error shape.
Closes#2
