The generator put `/* eslint-disable simple-import-sort/imports */` in
every generated image module, but only the two index files import
anything; eslint 10 reports the other 1533 as unused directives. It also
wrote import paths without the `.js` extension the committed index files
carry, so regenerating no longer reproduced them. Both fixed; the
generator now reproduces all 1535 committed files byte for byte.
