fix(acp): flush on error and filter whitespace text blocks in Claude API#828
Conversation
When process_response() fails (e.g. 529 overloaded), the error handler sends the error message but never flushes, leaving the ACP drain loop waiting indefinitely. Move flush_chunks() after the error block so it runs on both success and failure paths.

…ude API Skip messages with agent_visible=false in split_messages and split_messages_structured to prevent sending hidden context to the API. Guard all text content blocks against whitespace-only content which Claude API rejects with 400 "text content blocks must contain non-whitespace text".
