Until now the desktop app only ran from a source checkout, so Pithos was really usable only inside Theseus. electron-builder (the version Theseus uses) now makes an NSIS installer and a portable exe; s3d is still fetched on first run by the checksum-checked installer, so the app stays small and never ships an s3d it did not verify. Icons are rendered from ui/icon.svg. Quitting also no longer waits on idle keep-alive sockets before exiting.
