• Roll the driver from 20a2087ea43412b90c172c88faef80786ee18b8b to b4695e3eb2e6736d1a7b1fd255c4e94f78553660 (Playwright 1.65.0-next).
• Update the README to Chromium 157.0.8103.15 (revision 1252). The driver supplies the updated device user agents and the fix that hides FFmpeg console windows on Windows.
• No Python client or test ports remain. API generation and comparison produced no changes; mypy and all lint, generation, and test-registry checks passed.
• Chromium suites passed: 3,831 sync tests and 3,933 async tests. The unchanged async headful test HE-003 hit a browser crash once, then passed on retry and in a separate run with retries disabled. No test changes or new failure marks were needed.
