Chat UIs Are Lists Until They Aren't

Chat, AI streams, and logs don't behave like ordinary lists. TanStack Virtual now supports end-anchored virtualization for prepend-stable history, append-follow, and streaming output that stays pinned.

TanStack Virtual just got a lot faster, and finally handles iOS

A perf-focused release for TanStack Virtual. Cold mount at 100k items is 5x faster, a hilarious worst-case bug now runs 1382x faster, iOS Safari momentum scroll works for the first time, and scroll-up jank with dynamic items is gone by default.
