Subject: [PATCH] fix: hide typing indicator once assistant message appears
 during streaming

The "two diamond" bug was caused by GeminiTypingIndicator (which has its
own gem icon) rendering simultaneously with GeminiMessage (also has a gem
icon) once the first token arrived. Now the typing indicator only shows
while isLoading is true AND no assistant message exists yet (last message
is not role "assistant").
