Problem
When the agent streams a response, text arrives as agent_message_chunk events buffered and coalesced into a single agent_message. The 500ms flush debounce timer could fire mid-stream, which can let us have partial chunks into a premature agent_message.
Observed in truncated agent output in https://us.posthog.com/project/2/tasks/83e7bc2c-f543-40a7-8100-f0ac99102e4d?runId=44583200-aa9e-496b-b041-f92788d80bd3 (🧵 thread)
