[CheckboxGroup] Handling of Root toggle when there are disabled items in List

[colangeloproductions]

Steps to reproduce

https://master--base-ui.netlify.app/components/react-checkbox-group/#parent-checkbox

Steps:

1. Using the latest version 1.0.0-alpha.3
2. Render a CheckboxGroup with at least one disabled child element
3. Toggle the root checkbox

Current behavior

Currently when toggling the root checkbox in a group, all of the children get checked / unchecked (regardless if disabled). I have tried to do a filter for disabled and controlled on my end of the component but when doing so, I'm able to check all non-disabled / non-controlled children. But am then unable to uncheck anything via the root checkbox.

Expected behavior

The root checkbox shouldn't be able to change the checked state of any disabled / controlled items. But should always be able to check/uncheck all other children that allow so.

If this is something that is already possible and I am missing it, maybe you could add it to the docs
