CI / Build and push docker image (push) Successful in 1m5s
Both Docker stages now use python:3.14-alpine3.24. Since there is no combined uv image tag for python3.14-alpine3.24, the static uv binary is copied from ghcr.io/astral-sh/uv:0.13.1 into the builder stage. Requires Python 3.14, refreshes uv.lock, and updates the README badges.
