The perf job ran on the Playwright image, which bundles Chromium at
a non-standard path that Lighthouse's chrome-launcher cannot find —
the job failed at the healthcheck with 'Chrome installation not
found'.
Switch perf to node:24-bookworm and apt-install Debian's chromium
(/usr/bin/chromium), pointing CHROME_PATH at it. Preferred over
wiring CHROME_PATH to Playwright's bundled Chromium because the
latter couples the job to an exact @playwright/test-version vs
image-tag match that a Renovate bump would silently break.
The future ADR-0016 axe-core e2e job will use the Playwright image;
Lighthouse and Playwright want different things, so they get
different images rather than one that serves both poorly.
