refactor(di): removed @parent
BREAKING CHANGE
    The @parent annotation has been removed. Use @ancestor instead.
    @parent was used to enforce a particular DOM structure (e.g., a pane component is a direct child of the tabs component).
    DI is not the right mechanism to do it. We should enforce it using schema instead.
