👷 default local e2e to chromium only

[thomas-lebeau]

Motivation

Running yarn test:e2e locally currently runs all 4 default Playwright projects (chromium, chromium-pinned, firefox-pinned, webkit-pinned), making the local feedback loop very slow.

This ports the intent of the package.json change in #4618 but solves it inside playwright.config.ts so the test scripts and CI command stay untouched.

Changes

test/e2e/playwright.config.ts:

• When --project=<name> is not passed (typical local run), only the chromium project is registered → yarn test:e2e runs chromium only.
• When --project=<name> is passed (locally or in CI), all projects are registered and Playwright filters to the selected one(s) — so yarn test:e2e --project=firefox still works, and the CI matrix continues to run as before.
• The decision is taken once in the main process (from argv) and propagated to Playwright workers via an env var, since workers re-import the config without the original argv.
• needsPinnedServers() is simplified to only boot the pinned web servers when a pinned project is selected (no longer needs the "no args = all" branch).

Test instructions

• Local: yarn test:e2e should now run chromium only.
• Local: yarn test:e2e --project=firefox (or webkit, chromium-pinned, etc.) should still run that project.
• CI: the existing yarn test:e2e --project=$BROWSER matrix invocation is unchanged.

Checklist

• Tested locally
• Tested on staging

• Added e2e/integration tests for this change.
• Updated documentation and/or relevant AGENTS.md file

Preserve --project overrides for local E2E

When a developer follows the documented pinned-browser commands such as yarn test:e2e --project=firefox-pinned, this script now expands to Playwright with both --project=chromium and --project=firefox-pinned. Playwright's CLI treats --project as the specified list of projects, so the user-selected browser is no longer exclusive and Chromium always runs as well; this makes targeted local debugging and pinned-browser runs slower and can hide that the requested command did not run in isolation. Consider adding the default Chromium project only when the caller did not pass any --project option.
