Code Review

This pull request does a good job of cleaning up unused code, which improves code quality. I've left a couple of comments on the __exit__ methods that were modified. One is a high-severity issue regarding a potential resource leak in BrowserbaseComputer. The other is a medium-severity suggestion to improve the robustness of the cleanup logic in PlaywrightComputer. Addressing these will make the resource management more reliable.
