/**
 * TypingBubble — incoming-style chat bubble with animated typing dots and
 * the matching avatar. Rendered as the last child of the message list so
 * the dots occupy the exact slot the real message will land in; when the
 * message arrives the bubble shape stays put and the content morphs from
 * dots to text. Used for two cases:
 *
 *   1. Live typing event (agent / AI publishes `is_typing: true`) —
 *      rendered while `store.isTyping` is true.
 *   2. New-channel pending state — rendered while we wait for the server
 *      response to `POST /channels` (replaces the old `NewChannelLoader`
 *      so the empty-conversation placeholder and the live indicator share
 *      one component).
