Executing 'render test' requires building subpackage first

Hi,

From a clean install, I did:

cd render-tests
npm ci
npm run build
npm run test

which gave me the following output:

> render-test@1.0.0 test
> node dist/run_render_tests.js

node:internal/modules/esm/resolve:265
    throw new ERR_MODULE_NOT_FOUND(
          ^

Error [ERR_MODULE_NOT_FOUND]: Cannot find module '/home/pietervdvn/git/basemaps/render-tests/node_modules/@protomaps/basemaps/dist/esm/index.js' imported from /home/pietervdvn/git/basemaps/render-tests/dist/run_render_tests.js

}

Node.js v20.16.0

So I did:

cd node_modules/@protomaps/basemaps
npm ci
npm run build

after which the tests worked as expected. IMHO, building the subpackage should not be needed and is an extra barrier to new contributors.

Start in the render-tests package by reproducing the clean-install sequence and inspect dist/run_render_tests.js together with the @protomaps/basemaps package resolution. Determine why @protomaps/basemaps/dist/esm/index.js is absent after the documented setup. Done means npm run test succeeds without entering node_modules or building the subpackage manually.
