Marc-André Bombeck 626a95ff33 ci: give every job that runs the unit suite a browser
The hero-geometry check stopped skipping under CI in v1.38 and started failing
instead, which was the point: it had caught its own launch failure and passed
for months, measuring nothing. The install step went into the quality job of
`security.yml` and nowhere else, and a second job runs the same suite — the
auto-merge job for dependency bumps. Every Dependabot pull request has failed
since on `browserType.launch: Executable doesn't exist`, four of them on
2026-09-06 alone (run 34043840314), on an error that says nothing about the
bump. One workflow was fixed; the class was not.

That job installs the same headless shell now, off the same cache key. The
error the check throws names both jobs rather than sending a reader to the
workflow that was already correct, and a guard sweeps the workflow directory so
a third job cannot run the suite with no browser anywhere in it. Its limit is
written down: the sweep is file-scoped, so a workflow with two jobs where only
one installs still satisfies it.

Gates:

  CI=1, browser path hidden      exit=1, "This check is the gate in CI and it
                                 has no browser to measure with"
  CI=1, browser present          exit=0, 4 tests passed (it measures)
  install step deleted from the  guard fails: ["dependabot-auto-merge.yml"]

# The hero-geometry check in the unit suite renders the real panel in a
# real browser and measures the boxes, and it refuses to skip when CI is
# set — a check that skips measures nothing. This job runs the same suite
# as the quality job in `security.yml` and needs the same browser: without
# it every Dependabot pull request went red on a launch failure that said
# nothing about the bump (four of them on 2026-09-06 alone). Headless
# shell only, matching that job.
