The Rust CLI sends `null` for the `path` argument when it is not provided,
but the Zod schema only accepted `undefined`. This change updates the
`screenshotSchema` to allow `null` values for `path`, enabling the
`screenshot` command to work without a file path argument (outputting to stdout).

When connecting to a browser via CDP, particularly on Android, tabs with an empty URL can cause Playwright commands to hang indefinitely. This leads to a timeout in agent-browser.
This commit fixes the issue by filtering out any pages that have an empty `page.url()` during the CDP connection process. This prevents agent-browser from attempting to interact with these problematic tabs, resolving the timeout while preserving normal pages.
Added a unit test to verify that pages with empty URLs are correctly ignored. Also increased the timeout for a flaky screencast test to improve test suite stability.
