name: Build desktop

# Build the Tauri desktop installers (.deb + .AppImage) on every push to dev/main and
# upload them as workflow ARTIFACTS — a downloadable, per-commit build for testing the
# native shell. This is NOT a release: it's unsigned (no updater key) and creates no Gitea
# Release. Signed, versioned releases stay on release.yml (tag v* → .deb/.rpm/.AppImage +
# latest.json for the auto-updater). See wiki/decisions/desktop-shell-tauri.md.
