黄金三章检查工具 v2.0 (LLM-Driven)

功能：检测小说前三章是否符合"黄金三章"标准

v2.0 重大升级：
- 保留关键词预检作为快速模式
- 新增 LLM 深度评估模式（AI Native）
- 生成结构化评估 Prompt，解析 XML 评估结果

核心检查点：
- 第 1 章：300 字内主角出场 + 金手指线索 + 强冲突开局
- 第 2 章：金手指展示 + 初次小胜 + 即时爽点
- 第 3 章：悬念钩子 + 下一阶段预告 + 爽点密度 >= 1

使用方法：
python golden_three_checker.py --auto                    # 快速关键词模式
python golden_three_checker.py --auto --mode llm         # LLM 深度评估（推荐）
python golden_three_checker.py --auto --generate-prompt  # 仅生成评估 Prompt

LLM_EVALUATION_PROMPT = """你是一位网文编辑，专门负责评估小说开篇的"黄金三章"质量。

请根据以下标准，对这三章内容进行专业评估：

## 黄金三章标准

### 第 1 章核心检查点：
1. **主角 300 字内出场**：主角是否在前 300 字内登场？身份是否清晰？
2. **金手指线索**：是否有金手指/外挂的暗示或线索？
3. **强冲突开局**：开篇是否有足够强的冲突/危机/矛盾？

### 第 2 章核心检查点：
1. **金手指展示**：金手指是否有明确展示？读者能否理解其能力？
2. **初次小胜**：主角是否获得了第一次小规模胜利/成功？
3. **即时爽点**：是否有让读者感到爽快/满足的场景？

### 第 3 章核心检查点：
1. **悬念钩子**：章节结尾是否有悬念？能否驱动读者继续阅读？
2. **下一阶段预告**：是否暗示了接下来的剧情走向/新挑战？
3. **爽点密度**：本章是否至少有 1 个明显的爽点场景？
