Add the official FSF license text, a copyright/license header in
server.js, license metadata in package.json, and a License section in

Express service that authenticates Gitea deliveries, verifies the HMAC
signature, builds a readable text summary for push/pull_request events,
and forwards it to the Anthropic routines API with the headers Gitea
can't set itself. Includes in-memory delivery dedup, structured logging,
.env.example, and a Dockerfile for deployment behind nginx.
