 - ElevenLabs: add retry/backoff for 429/5xx and include content-type in errors for debugging.
 - Talk Mode: align to the gateway’s main session key and fall back to history polling when chat events drop (prevents stuck “thinking” / missing messages).
 - Talk Mode: treat history timestamps as seconds or milliseconds to avoid stale assistant picks (macOS/iOS/Android).
-- Chat UI: dedupe identical history messages to avoid duplicate bubbles.
+- Chat UI: clear streaming/tool bubbles when external runs finish, preventing duplicate assistant bubbles.
 - Chat UI: user bubbles use `ui.seamColor` (fallback to a calmer default blue).
 - Talk Mode: wait for chat history to surface the assistant reply before starting TTS (macOS/iOS/Android).
 - iOS Talk Mode: fix chat completion wait to time out even if no events arrive (prevents “Thinking…” hangs).
