Description: Summary Rework the thinking indicator into a single fixed-height slot on the last turn — shimmer swaps with arriving output via opacity only, so it never shifts the transcript (previously 4 mount/unmount sites caused up/down jumps) Contextual labels derived from the stream (Thinking/Dispatching/Returning); dispatch yields to the agent lane's own shimmer once open Fix auto-scroll jerk: followToBottom spawned a new chase loop per animationstart (up to 20 concurrent writers snapping the scroll) — now folded into createSmoothBottomChase via a deadline-extending kickUntil Prevent transcript drops from transient markdown re-parse shrinks: sizer min-height floored at the scrolled-to extent while streaming Type of Change Improvement Testing Verified with in-browser scroll instrumentation (0 stacked scroll writers, 0 downward transcript moves during streaming, 0px phantom space at settle); vitest 107/107 in the touched tree; lint + strict boundary validation pass Checklist Code follows project style guidelines Self-reviewed my changes Tests added/updated and passing No new warnings introduced I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)
