TermosTabBar class
Top, horizontally scrollable tab strip with a glow indicator that tracks the active TabController (including swipe progress on a TabBarView).
Tabs are sized to their own label widths (variable-width, not equal-flex). When the combined tab width exceeds the available viewport, the strip becomes horizontally scrollable and animates the active tab into view.
Visuals come from TermosThemeData.tabBar (effects) and TermosThemeData.metrics (layout). Heavy effects (dot grid, glow halo) follow TermosThemeData.heavyEffectsEnabled unless overridden via heavyEffectsEnabled on the widget.
A TabController must be available — pass one explicitly via controller, or rely on a DefaultTabController ancestor.
