Move minimumHeaderHeight state from PagerTabBar up to PagerWithHeader so it can be shared with child tabs. Compute collapsedHeaderHeight as minimumHeaderHeight + tabBarHeight and pass it through PagerWithHeaderChildParams alongside headerHeight. This gives each tab access to the collapsed header offset for scroll indicator positioning. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
