Playwright Browser Automation

Provides primitives for browser automation: dev-server detection, a script runner (scripts/run.js), and helper utilities (scripts/lib/helpers.js).

Critical workflow

1. Detect dev servers first for localhost testing:

   node -e "require('scripts/lib/helpers').detectDevServers().then(s => console.log(JSON.stringify(s)))"
   

   One server → use it. Multiple → ask which. None → ask for a URL.

2. Write generated scripts to /tmp/playwright-test-*.js — never into scripts/ or the user's project.

3. Visible browser by default (headless: false). Headless only when the user asks.

4. Parameterize the target URL at the top of the script as TARGET_URL.
