CI / Build and push docker image (push) Successful in 1m14s
docker: base the image on alpine
Both build and runtime stages now use python3.13-alpine3.23 (uv image
for the builder, python image for the runtime), with BusyBox
addgroup/adduser for the non-root xmcp user. All native dependencies
ship musllinux wheels, so no compiler is needed in the builder.
