Shipment Tracking API

Problem/Feature Description

A logistics company needs a NestJS API for tracking shipments. Build the initial project scaffold following NestJS best practices.

Requirements:

1. A shipments feature module with POST /shipments (create), GET /shipments (list all), and GET /shipments/:id (get one) endpoints
2. A DTO for creating shipments: trackingNumber (non-empty string), origin (string), destination (string), weightKg (positive number)
3. A logging interceptor that logs HTTP method, URL, and request duration in ms
4. Proper error handling and input validation configured globally
5. A stub service (in-memory array storage is fine)

Follow NestJS best practices for project structure, error handling, validation, and response formatting.
