Run node tests when coverage is configured for node

Closes #10

// .ocularrc.js
coverage: {
  test: 'browser' // now runs headless-browser tests in CI
},

// .ocularrc.js
coverage: {
  test: 'node' // runs node tests in CI
},

This would change deck to run headless-browser tests in ci as well based on this config:

Here's a test in hubble showing node tests were running: https://github.com/visgl/hubble.gl/actions/runs/13976991475/job/39133098199

Then when I hacked around this the browser tests now run as expected: https://github.com/charlieforward9/hubble.gl/actions/runs/13977630524/job/39135198338
