feat(exam_pkg): 优化出题系统稳定性与推理模型适配
- core/llm_utils: MiMo模型自动注入thinking=disabled参数,全局生效 - config: 新增LLM_DISABLE_THINKING配置项(默认true) - generator: 推理模型自适应max_tokens(1.5x)、429限流重试+指数退避、v2管线补题机制 - generator: analyze_document_for_exam新增max_total参数控制AI出题上限 - generator: validate_questions_schema兼容type和question_type字段 - grader: 主观题max_tokens从1000提升至2000、fuzzy_match增加编辑距离容错 - manager: results变量初始化防NameError、透传max_total参数 - api: /exam/generate-smart支持max_total请求参数
