Jon Seager 74e3b600fc chore: Switch e2e tests to Chrome for Testing via mise
Replace snap-installed Chromium/chromedriver with Chrome for Testing
installed via npx @puppeteer/browsers. Binaries live in
$MISE_DATA_DIR/chrome-for-testing/ with version-agnostic path lookup.

Add install-e2e mise task and required apt packages to README and CI.
