E2E: parallel workers

[phyllis-sy-wu]

Addressed #7268

WHY are these changes introduced?

E2E tests currently run sequentially with 1 worker, making the suite slow (~25 min on CI). With per-test store creation (PR #7279), each store-dependent test adds ~30s of overhead, compounding the problem.

WHAT is this pull request doing?

Enables parallel test execution in playwright.config.ts:

• fullyParallel: true — tests run concurrently across workers
• workers: 3 — 3 parallel Playwright workers
• globalTimeout: 20 * 60 * 1000 — reduced from 35 min to 20 min (parallel execution is much faster)
• GitHub Actions timeout-minutes reverted from 40 back to 20 (no longer needs the temporary bump from E2E: temporary time limit bump #7282)

Why 3 workers, not more? Tested with 4 and 5 workers, but the app-scaffold test consistently failed on CI (fine locally). That test uses npm (not pnpm) with the full reactRouter template to mimic real user behaviour. On CI runners (2-core Ubuntu), 4+ concurrent workers cause npm install to fail due to resource contention (network/disk I/O). 3 workers is the sweet spot — still a significant speedup while keeping npm-based tests reliable.

How to test your changes?

# Run full suite — should complete in ~8-12 min instead of ~25 min
pnpm --filter e2e exec playwright test

# Verify no port conflicts with headed mode
E2E_HEADED=1 DEBUG=1 pnpm --filter e2e exec playwright test

Checklist

• I've considered possible cross-platform impacts (Mac, Linux, Windows)
• I've considered possible documentation changes
• I've considered analytics changes to measure impact
• The change is user-facing, so I've added a changelog entry with pnpm changeset add

Differences in type declarations

We detected differences in the type declarations generated by Typescript for this branch compared to the baseline ('main' branch). Please, review them to ensure they are backward-compatible. Here are some important things to keep in mind:

• Some seemingly private modules might be re-exported through public modules.
• If the branch is behind main you might see odd diffs, rebase main into this branch.
