问题： 探针拦截（suggestion mode / warmup / max_tokens=1 haiku）的模拟响应以及 Gemini/Antigravity 兼容层生成的 message ID 不符合 Anthropic 官方 API 格式， 容易被客户端识别为非正宗响应。 修复： 1. generateRealisticMsgID()：msg_bdrk_ + 24字符 → msg_01 + 22位 Base62 （与官方 API 返回的 msg_011CdS6b8gAhoKWdW9jE87Zs 格式一致） 2. 去掉固定的 msg_mock_suggestion / msg_mock_warmup，统一使用随机 ID 3. 流式响应格式对齐官方： - message_start 增加 stop_details/cache token 字段 - content_block_start 字段顺序修正 - message_delta.usage 只含 output_tokens 4. 非流式响应：增加 stop_details:null，移除非标准 total_tokens 5. Gemini Messages/ChatCompletions 兼容层：msg_ + hex → msg_01 + Base62 6. Antigravity response/stream transformer：msg_ + 12位 → msg_01 + 22位 Base62 验证方式：对照 Anthropic 官方 API 实际响应格式确认。
