Getting started

• Installation — composer, config, migrations, artisan verification.
• Testing — Postal::fake(), the InteractsWithPostal trait and fake connections.
• Install with an AI assistant — a copy-paste prompt that does the whole setup.
• Artisan commands — install, doctor, ping, tail, message, webhook-key.
• End-to-end suite — the suite that runs against a real Postal install in Docker.
