The app has iPodderX's own icon, and a way onto the Mac

The 2004 icon, from ipodderx-rs's apple-touch-icon.png, which at 180px is
the largest square copy that survives anywhere -- so the sizes above it are
upscaled and soft, and a real 1024px original would be worth having if one
turns up.

Every entry in the icon set gets its own file even where two are the same
pixels, because the asset compiler collapses entries that share a filename
and the first attempt produced an icns with four of the ten sizes.

tools/install-mac.sh builds Release for Catalyst and replaces the copy in
/Applications. It quits the running app first, or the replacement is the
one still in memory, and it sets DEVELOPER_DIR rather than relying on
xcode-select, which on this machine still points at the command line tools.
