v0.1.4 fixes DeepSeek integration in Oc-go-cc: adds reasoning_content placeholders for text-only assistant turns, detects and round-trips thinking content in tool_use blocks, and disables thinking mode when absent to prevent API errors.

Why it matters: Update to v0.1.4 if running Oc-go-cc with DeepSeek thinking-enabled conversations to prevent API errors and ensure reasoning content persists across assistant turns and tool interactions.
