What was on git could not be installed. foundry-module/ referenced core/ rather
than containing it, so an installed copy had no generator at all — it only ever
worked here because the live module directory had core/ copied in by hand.
core/ is now vendored into foundry-module/module/core/, minus cli.mjs and
test.mjs which are desk tools. module.json points manifest and download at
release assets, the way mapwright distributes, so a remote server can install by
URL without reaching into the repo tree.
