Summary

• Keep the Node.js integration job and add a Bun job for the same Chromium/WebKit and Ruby version matrix.
• Use stable Bun 1.4.3, not a canary, for the Bun integration and example jobs. Keep the Windows check on Node.js.
• Run the Playwright CLI and driver with Bun, and accept the equivalent PFX passphrase error wording from Bun.

Verification

• Rebasing on main brings in Playwright 1.64.0, including the upstream client-certificate fix.
• On macOS arm64 with Bun 1.4.3 and Chromium, the full integration suite on main ran 1,259 examples with one PFX-message assertion failure and 26 pending. The self-signed client-certificate case passed, including 10 repeated runs.
• With this PR applied, the client-certificate spec passed: 10 examples, 0 failures, 1 pending. The example spec passed: 64 examples, 0 failures, 3 pending.
• Workflow YAML parsing and git diff --check passed. The Windows workflow now matches main.

The Windows Node.js check passed on the latest commit. The Linux integration matrix is still running.
