refactor(browser): improve browser path management

Implement more robust browser executable path handling using playwright's built-in browser management. This change:
- Adds async browser path resolution
- Implements path caching in the home folder
- Removes hardcoded browser paths
- Adds httpx dependency
- Removes obsolete test result files

This change makes the browser path resolution more reliable across different platforms and environments.
