Subject: [PATCH] fix: hide FAB on Reader tab, fix tab bar collapse during
 auto-scroll, position glass bar bottom-right
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. FAB hidden when selectedTab == 2 (Reader) — no plus button
   on Reader since it's for food logging

2. Auto-scroll now notifies original UIScrollViewDelegate via
   scrollViewDidScroll after each contentOffset change — this
   triggers tabBarMinimizeBehavior so the tab bar collapses
   during auto-scroll just like manual scrolling

3. Glass control bar positioned bottom-right (like Photos search
   icon) instead of bottom-center
