packages/ui/src/components/chat/MobileSessionStatusBar.tsx
- What: Added `min-w-0` to the title row flex container and `flex-1 min-w-0` to the session title span inside `SessionStatusHeader`.
- Why: The flex container had `min-width: auto` (browser default), causing the title to expand beyond its constrained parent and bleed over the running/unread indicators and New button. `truncate` was a no-op without a width ceiling on the span. Fixes#556.
