- Add dedicated API logger (api-logger.ts) with winston daily rotation - Create Fastify plugin (api-logging.plugin.ts) to intercept all API requests/responses - Log request start, body, response, errors, and summary with precise timestamps - Auto-mask sensitive data using existing sanitizeObject utility - Register API logging plugin in NestJS bootstrap (server/main.ts) - Add npm run dev script with cross-env for automatic DEBUG on Windows - Install cross-env as devDependency for cross-platform env vars
