Conversation mode was only reachable via a small icon by the composer, which is
easy to miss on a fresh session. Inject a prominent, centred 'Start
conversation' button into the empty new-chat state (#emptyState), below the
subtitle and above the suggestions, so it sits in the vertical centre of the
screen. It is created only when local voice is available, honours the same
show/hide preference as the composer toggle, and enters conversation mode
through the same activate() path. Fully guarded so it degrades to nothing if the
empty state is absent. New probe scenario verifies it is created, visible, and
opens the conversation overlay on press.
