Implement Anthropic Computer Use as a sample app

[juecd]

Implements the Anthropic CU reference implementation in Typescript and replaces xdotool + gnome-screenshot with Playwright.

I'll add the Python version after this.

kernel deploy index.ts --env ANTHROPIC_API_KEY=XXX
kernel invoke ts-cu cu-task --payload '{"query":"navigate to https://news.ycombinator.com and return the title of the first result. JUST RETURN THE TITLE, DONT WRITE ANYTHING ELSE."}'
