feat: add playwright integration tests for browser automation through firewall

[Copilot]

Adds integration test suite validating Playwright browser automation works correctly through the firewall with domain whitelisting.

Changes

• Test suite (tests/integration/playwright-testing.test.ts): 6 test cases covering:

  • Allowed/blocked domain enforcement for browser navigation
  • Page interaction, multi-page navigation, screenshot capture
  • Uses heredoc pattern to avoid shell escaping issues with inline Node.js code

• Example script (examples/playwright-automation.sh): Demonstrates real-world usage with GitHub navigation and screenshot capture

• Dependencies: Added playwright and @playwright/test to dev dependencies

Key Implementation Detail

Playwright requires infrastructure domains for operation:

• registry.npmjs.org, npmjs.com - npm package downloads
• playwright.azureedge.net - Chromium browser binary downloads

Tests use 180-240s timeouts to account for browser download and installation on first run.

sudo -E awf \
  --allow-domains github.com,registry.npmjs.org,playwright.azureedge.net,npmjs.com \
  -- npx -y playwright@latest install chromium && node test.js

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• 8.8.4.4
  • Triggering command: REDACTED, pid is -1 (packet block)
• 8.8.8.8
  • Triggering command: REDACTED, pid is -1 (packet block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Closing PR to reduce backlog. The work is tracked in issues #102 and #85 (Playwright testing). Will fix it later.
