scroll_sync_tabs 0.1.0

Keep a TabBar and a scrollable list of sections in sync both ways - scrolling selects the tab, tapping a tab scrolls to the section.

0.1.0

• Initial release.
• ScrollTabController<T> keeps a tab strip and a scrollable section list in sync in both directions, with scrollTo/jumpTo, runtime updateItems, a mutable pinnedHeaderExtent, and a two-phase (estimate, then correct) scroll for sections whose anchors are not yet mounted.
• ScrollTabBar<T> forwards every TabBar styling parameter, with a .builder constructor for raw Tab widgets, leading/trailing slots, and a static ScrollTabBar.sliver<T>(...) helper that wraps the strip in a pinned SliverPersistentHeader.
• ScrollTabAnchor marks a section for a controller without affecting layout.
