Add browser/Chrome ecosystem domain group for browser-testing projects

[Mossaka]

Problem

deno/fresh (and potentially other browser-testing projects) need Chrome/Google domains for integration tests that launch headless Chrome. 81 requests were blocked in v6.

Blocked Domains

• accounts.google.com (20 requests)
• www.google.com (24 requests)
• fresh.deno.dev (10 requests)
• optimizationguide-pa.googleapis.com (16 requests)
• redirector.gvt1.com (3 requests)
• safebrowsing.googleapis.com (2 requests)
• update.googleapis.com (6 requests)

Suggested Implementation

Add a browser or chrome ecosystem domain group:

• *.google.com
• *.googleapis.com
• *.gvt1.com
• fresh.deno.dev (Deno-specific)

This would benefit any project using headless Chrome/Puppeteer/Playwright for testing.

Evidence: v6 build-test experiment, deno/fresh workflow run.

Add precise domains, not *
