fix: make npm test cross-platform

node --test <directory> walks the directory on Node 18 but tries to
require it as a module on Node 22 (windows-latest ships 22.x), so CI
was failing with MODULE_NOT_FOUND. Replace the directory argument
with a small enumerator script that reads the compiled test dir and
passes every *.test.js file explicitly to node --test — works on any
node version on any OS.
