# Builds the Flatpak bundle and runs flatpak-builder-lint, the same gate
# Flathub applies to submissions, so manifest/metadata regressions are caught
# before a Flathub PR. Also verifies cargo-sources.json is in sync with
# Cargo.lock, since a stale vendored-crate list silently breaks the offline
# build only on Flathub's servers.
