mir-backend-node-nestjs

Make It Right (NestJS module). NestJS + TypeScript specific reliability augmentation. Use alongside mir-backend and mir-backend-node when the target stack is NestJS — it carries the mechanical footguns that the framework-agnostic tiers deliberately omit: singleton DI scope bleeding request state across users, the full execution-order pipeline (middleware → guards → interceptors → pipes → handler → interceptors → exception filters), ValidationPipe with whitelist and forbidNonWhitelisted to stop mass assignment, and offloading durable work to a queue (Bull/BullMQ) rather than running it in a request. TRIGGER only when the Node backend stack is NestJS — building, reviewing, or debugging a NestJS controller, provider, guard, pipe, interceptor, or exception filter. Always loads TOGETHER WITH mir-backend (the gates) and mir-backend-node (V8 event-loop / process-model concerns: blocking, worker_threads, unhandled rejections, backpressure, timeouts); this module only adds NestJS library mechanics. SKIP for Express, Fastify (standalone), Hapi, Koa, or any non-NestJS stack (those get their own mir-backend-node-<framework> module), and for non-Node runtimes.
