dist.sh builds versioned, signed artifacts for both apps from a git tag

(semver drives Android versionCode/versionName and package.json). The
build-image/ Dockerfile pins the same toolchain for a portable,
containerized Gitea Actions runner (build-image.sh builds and pushes
it) so releases don't depend on any one machine's local setup.
Pushing vX.Y.Z now builds and publishes a Gitea Release automatically.
