feat(docker): use pre-built GHCR image in docker-compose by default (#25)

docker-compose.yml now references ghcr.io/ulsklyc/oikos:latest so users
can start the app with a single 'docker compose up' without cloning or
building locally. The build: . entry is retained for contributors who
want to build from source with --build.

README Quick Start updated to document both the no-clone path (curl
docker-compose + .env.example) and the build-from-source path.
