Add HyperbrowserBrowser

[shrisukhani]

Add Hyperbrowser Support to openai-cua-sample-app

This PR adds support for Hyperbrowser, a browser infrastructure service that provides fast, reliable, and scalable remote browsers for developers using OpenAI’s CUA API.

Key Changes:

• Added HyperbrowserBrowser implementation
• Updated README with setup instructions for Hyperbrowser
• Fix the model name - change to computer-use-preview
• Fix the tool name - change to computer_use_preview

Why Hyperbrowser?

• Optimized for parallelized browsing – spin up 100s of browsers in seconds
• Developer-friendly SDKs – available in Python and Node
• Live preview URLs – for real-time browser monitoring
• Persistent sessions & storage – save sessions, cookies, and more with just two lines of code

I think this PR expands the options available to developers using the CUA API, making it easier to choose the right execution environment for their needs. Looking forward to feedback! :)

Full disclosure: I’m the Founder of Hyperbrowser.

tl;dr please adhere to new computer structure and contributing process

Hi! Thanks for your contribution – we'd love to get it reviewed and merged. To better support custom CUA computers we've created a contrib directory to co-locate community contributions and automatically run basic smoke tests.

Please make sure you complete the three main steps:

1. Move computers/contrib and update configs
2. Pass tests & do manual testing
3. Submit PR with required information

These are explained in detail in the contributing section of the README.

Thanks again!
