screenshot() calls activate() which steals window focus on every capture

[FredrikNoren]

Problem

The screenshot() method in handler/page.rs unconditionally calls self.activate() before capturing:

https://github.com/mattsse/chromiumoxide/blob/main/src/handler/page.rs#L387

pub async fn screenshot(&self, params: impl Into<ScreenshotParams>) -> Result<Vec<u8>> {
    self.activate().await?;  // sends ActivateTargetParams
    // ...
}

This sends Target.activateTarget via CDP, which brings the browser window to the OS foreground on every screenshot. For automation agents that take screenshots every few seconds (e.g. after each action), this makes the browser repeatedly steal focus from whatever the user is working on.

Expected behavior

CaptureScreenshot works fine via CDP without activating the target first — the screenshot is captured from the page's render tree regardless of window focus. The activate() call is unnecessary for single-tab use cases and harmful for headful automation where the user wants to multitask.

Suggested fix

Either:

1. Remove the activate() call from screenshot() entirely, or
2. Make it opt-in via a parameter on ScreenshotParams (e.g. activate_before_capture)

Workaround

Calling page.execute(CaptureScreenshotParams { format: Some(Png), .. }) directly bypasses the issue.

Environment

• chromiumoxide 0.8.0
• macOS (though the issue applies to any OS where Target.activateTarget brings the window to front)

Feel free to send a PR.
We should retain the option to call activate via a param, I am on the fence what the default should be. If you make it false by default you need to add a breaking change line in the changelog
