+- 仅提取文本中明确提到的信息，不要推测
+- 如果文本中没有可提取的用户画像信息，返回空的 user_metadata 对象

+- profile.interests：用户主动表达兴趣的话题或领域标签
+- behavioral_hints.learning_stage：学习阶段（初学者/中级/高级）
+- behavioral_hints.preferred_depth：偏好深度（概览/技术细节/深入探讨）

+- **aliases_to_remove**：用户明确否认的别名，包括：
+  * 用户说"我不叫XX了"、"别叫我XX"、"我改名了，不叫XX" → 将 XX 放入此数组
+  * **严格限制**：只将用户原文中**逐字提到**的被否认名字放入，不要推断关联的其他别名

+- profile.interests: Topics or domain tags the user actively expressed interest in
+- behavioral_hints.learning_stage: Learning stage (beginner/intermediate/advanced)

+  * How others address the user: e.g. "My colleagues call me Johnny", "People call me Mike"
+  * Only extract names that appear VERBATIM in the text — never infer or fabricate
+  * Do NOT extract: names the user gives to the AI, third-party people's own names, placeholder words like "User"/"I"
+  * If no new aliases, return empty array `[]`
+- **aliases_to_remove**: Aliases the user explicitly denies, including:
+  * User says "Don't call me XX anymore", "I'm not called XX", "I changed my name from XX" → put XX in this array
+  * **Strict rule**: Only include the exact name the user **verbatim mentions** as denied. Do NOT infer or remove related aliases
