fix(cdp): accept Audits domain as no-op for Puppeteer compatibility (#57) (#80)

Puppeteer's FrameManager.initialize calls Audits.enable on connect.
Without it puppeteer.connect() fails with "Unknown domain: Audits"
before any user code runs. Playwright doesn't enable Audits, which is
why the workaround in #57 sidesteps the issue.

Add Audits to the existing accepted-but-no-op domain list, alongside
Log/Performance/Security/etc. that already swallow Puppeteer's connect
chatter. No new module needed.
