//! URL shortener service
//!
//! A small but complete service: API-key protected management API, public
//! redirects, click counting, expiry, rate limiting, persistence to a JSON
//! file, health check and a generated OpenAPI document.
//!
//! Configuration (environment):
//!   PORT            listen port (default 3000)
//!   API_KEYS        comma separated keys allowed to manage links (default: demo-key)
//!   BASE_URL        public URL used in responses (default http://localhost:PORT)
//!   DATA_FILE       JSON file for persistence (default: in-memory only)
//!
//! Run:   cargo run --example shortener
//! Try:   curl -s -X POST localhost:3000/api/links -H 'x-api-key: demo-key' \
//!             -H 'content-type: application/json' -d '{"url":"https://example.com/docs"}'
//!        curl -i localhost:3000/<code>
//!        curl -s -H 'x-api-key: demo-key' localhost:3000/api/links/<code>
//!        curl localhost:3000/openapi.json
