What changes were proposed in this PR?

GitHub has started moving ubuntu-latest runners to the Ubuntu 26.04 image (Image: ubuntu-26.04, version 20261012.601). On those runners, build / frontend (ubuntu-latest, 24.19.0) fails at Install Playwright Chromium, before any test runs:

Error: ERROR: Playwright does not support chromium on ubuntu26.04-x64

The rollout is gradual, so it hits a random subset of runs: main's last ubuntu frontend run (2026-10-21) still landed on 24.04 and passed, while #9088's run on 2026-10-22 landed on 26.04 and failed. Nothing in the repository changed.

The cause is the pinned playwright 1.59.1, which predates Ubuntu 26.04 support. 1.61.0 is the first release whose host-platform detection and browser registry know ubuntu26.04. This bumps playwright to 1.64.1 (the current release, and the version Renovate's grouped #7896 also targets), with the lockfile regenerated by the vendored Yarn 4.14.1:

• playwright / playwright-core: 1.59.1 → 1.64.1.
• fsevents@2.3.2 drops out of the lockfile; it was an optional macOS dependency of the old playwright only.

@vitest/browser-playwright 4.1.11 declares playwright: "*" as its peer, and playwright is a dev dependency, so no LICENSE-binary entry changes.

release/v1.2 and release/v1.3 pin the same playwright 1.59.1 and run the same install step, and the change applies to both cleanly, so this carries their backport labels. release/v1.1 does not use Playwright.

Any related issues, documentation, discussions?

No issue filed — the regression originates outside the repository and this PR is the unblock, as with #7710 and #9064.

How was this PR tested?

The failure itself depends on which runner image GitHub assigns, so it cannot be reproduced on demand here or locally. The bump was checked locally on Windows, from frontend/:

• node .yarn/releases/yarn-4.14.1.cjs install --immutable --inline-builds: success.
• node .yarn/releases/yarn-4.14.1.cjs playwright install chromium: downloads Chrome Headless Shell 156.0.8078.4 (playwright build v1248).
• node .yarn/releases/yarn-4.14.1.cjs ng run gui:test-browser: 3 files, 23 tests, all pass.

This PR's own CI then confirmed the fix on the new image: build / frontend (ubuntu-latest, 24.19.0) and both backport legs (release/v1.2, release/v1.3) ran on Image: ubuntu-26.04 and passed, including the Install Playwright Chromium step.
