+ * Most OpenAI-compatible SDKs echo the whole history on the next turn,
+ * so Kimchi's upstream counts the scratch block as input tokens.
+ * Multi-turn conversations balloon to 100k+ input tokens and the model
+ * starts returning empty content.

+ * `stripReasoningContent` is intentionally conservative: it only strips
+ * `reasoning_content` that is clearly a real thinking block. The 1-char
