ci(guide): run browser tests explicitly [Codex]

[jderochervlk]

The guide's Browser Mode suite was configured but not run by the pull-request workflow, and its pinned Chromium cache was not exposed inside the Playwright container.

This configures the existing Playwright container cache and gives the guide suite its own named CI step alongside the docs suite. Browser-test failures will now be visible independently in pull requests.
