A small fixed bottom-right overlay (VersionBadge) shown app-wide — on the home
page AND inside the loaded editor — surfacing this build's release tag and a
link to the source. The tag links to the exact commit when known (the pcbjam
commit pins the kicad + wxwidgets submodule revisions → our GPLv3
corresponding-source pointer, mirroring site Footer's BUILD_SHA), else the tag's
release page, else the repo root.
build-demo.mjs injects VITE_APP_TAG / VITE_GIT_SHA / VITE_REPO_URL (new --repo
flag, defaults to github.com/emergence-engineering/pcbjam).
