fix: run every web-test-runner suite in one Gate slot

The root browser suite and the website and gallery suites each start a
web-test-runner on its default port 8000. With the root suite in one
Gate slot and the in-repo app suites in another, the two overlapped on
a signoff run and the later one fetched its test modules from the
wrong server (every test failed with "Failed to fetch dynamically
imported module ... localhost:8000"). Two earlier runs missed it only
by timing. The root browser suite and the in-repo app group now share
one sequential slot, which costs no wall-clock because the e2e group
is the floor, and framework-dev.md names the rule.
