fix(discord): collapse cron announce text

 ### Fixes
 
+- Discord/cron: deliver text-only isolated cron and heartbeat announce output from the canonical final assistant text once, avoiding duplicate Discord posts when streamed block payloads and the final answer contain the same content. Fixes #71406. Thanks @alexgross21.
 - Control UI/WebChat: hide heartbeat prompts, `HEARTBEAT_OK` acknowledgments, and internal-only runtime context turns from visible chat history while leaving the underlying transcript intact. Fixes #71381. Thanks @gerald1950ggg-ai.
 - Control UI/chat: keep optimistic user and assistant tail messages visible when a final history refresh briefly returns an older snapshot, preventing message cards from flash-disappearing until the next refresh. Fixes #71371. Thanks @WolvenRA.
 - Talk/TTS: resolve configured extension speech providers from the active runtime registry before provider-list discovery, so Talk mode no longer rejects valid plugin speech providers as unsupported.
