This commit includes several updates to the crawl4ai package, including changes to the browser manager and content scraping strategy. The version number has been updated to 0.7.1. Significant modifications have been made to the documentation, including updates to the release notes for version 0.7.0 and the addition of release notes for version 0.7.1. Examples and core documentation have also been updated to reflect the changes in this version. Additionally, a new simple API test has been added to the Docker tests.
These changes were made to improve the functionality of the crawl4ai package and to provide clearer, more up-to-date documentation for users. The new test will help ensure the API is working as expected.
BREAKING CHANGE: The updates to the browser manager and content scraping strategy may affect how these components interact with the rest of the package. Users should review the updated documentation for details on these changes.

Documentation:
- Comprehensive guide at docs/md_v2/advanced/virtual-scroll.md
- API reference updates in parameters.md and page-interaction.md
- Blog article explaining the solution and techniques
- Complete examples with local test server
Testing:
- Full test suite achieving 100% capture of 1000 items
