While a multi-step agent turn is "thinking between tool steps", the
assistant identity name (e.g. the role name) was rendered twice, stacked:
once by the assistant message row (MessageItem) and once by the standalone
TypingIndicator below it. The indicator's name label only makes sense when
it stands in for a not-yet-started assistant row; between steps the row
above already shows the same name.
Render the indicator's dimmed name label only when it is standalone (no
assistant row at the tail yet); otherwise show just the "Thinking…" dots.
- typing-indicator.tsx: optional showName prop (default true); the name
label renders only when showName !== false
- message-list.tsx: exported typingIndicatorShowsName(messages) helper;
pass showName to the indicator at the render site
- typing-indicator-shows-name.test.ts: unit-cover the four cases
