Subject: [PATCH] fix: remove AnimatedVisibility from chat bubbles to fix
 LazyColumn scroll limit

AnimatedVisibility with visible=false starts items at zero height. Inside a
reverseLayout LazyColumn, this causes the list to miscompute total content
height, preventing items beyond the visible viewport from being composed.
This was limiting the chat to ~9 visible messages that filled the screen.
