Switch the compose example from local build to pulling the full registry path git.rtynski.pl/rtynski/hy2026, default the host port to 8075 and add a commented external ovh_net network.
Add a multi-stage Dockerfile (Vue build + .NET 10 publish) and a docker-compose service exposing port 8080 with a single bind mount ./data -> /app/data for SurrealDB persistence. Include an example compose file, a .dockerignore, and document Docker usage and version 0.0.1 in the README.
