Nice fix for reasoning block formatting – the regex /([.!?])\*\*([^*\n]+)\*\*/g inserts double newlines before bold headers following sentence-ending punctuation, which should improve readability. Consider extracting this formatting logic into a helper (e.g. formatReasoningMessage) for better testability and reuse. Also, the preliminary check if (reasoningMessage.includes("**")) may be redundant since the regex replace safely does nothing if no match is found.
