SSBU Online Deluxe updated to v1.4.1.
The mod is bundled inside the .nro, not downloaded, so without a new Prelude release you
stayed on the August build with nothing telling you so.
Two files actually change (libssbu_online_deluxe.nro and libssbusync.nro). The other five
the upstream archive ships are byte for byte identical to what was already bundled, so they
were left alone.
Also lands two fixes that shipped in v3.3.9 but had never been merged into main: the three
BCAT CDN hosts being redirected (Splatoon 3 error 2122-2403 on console), and the update check
deriving its version from APP_VERSION so the updater stops offering an update forever.
