feat: Enhance Processor, RuleExtractor, and Renderers with type hints and improved documentation

- Added type hints to Processor methods for better clarity and type safety.
- Improved documentation for Processor methods, including detailed descriptions of parameters and return types.
- Refactored RuleExtractor to support optional configuration file loading and added error handling for file operations.
- Enhanced MarkdownRenderer to handle both list and dictionary inputs, with improved rendering logic.
- Created comprehensive examples and tests for all components, ensuring robust functionality and error handling.
- Added example rules for D&D 5E and structured output files for various formats (JSON, HTML, Markdown).
- Established a testing framework with clear instructions and coverage reporting.

+# ConventionalRP 测试套件
+
+本目录包含 ConventionalRP SDK 的所有单元测试。
+
+## 测试文件
+
+- `test_parser.py` - Parser 解析器测试
+- `test_processor.py` - Processor 处理器测试
+- `test_rule_extractor.py` - RuleExtractor 规则提取器测试
+- `test_renderers.py` - 渲染器测试（HTML/JSON/Markdown）
+- `test_pyo3.py` - PyO3 Rust 扩展测试
+
+## 运行测试
+
+### 运行所有测试
+
+```bash
+python tests/run_tests.py
+```
+
+### 运行单个测试文件
+
+```bash
+python -m unittest tests/test_parser.py
+python -m unittest tests/test_processor.py
+```
+
+### 运行特定测试类
+
+```bash
+python -m unittest tests.test_parser.TestParser
+```
+
+### 运行特定测试方法
+
+```bash
+python -m unittest tests.test_parser.TestParser.test_load_rules_success
+```
+
+## 测试覆盖率
+
+要查看测试覆盖率，请安装 `coverage` 并运行：
+
+```bash
+pip install coverage
+coverage run -m unittest discover -s tests -p "test_*.py"
+coverage report
+coverage html  # 生成 HTML 报告
+```
+
+## 测试数据
+
+测试使用临时文件来模拟规则文件和日志文件，测试完成后会自动清理。
+
+## 添加新测试
+
+创建新的测试文件时，请遵循以下约定：
+
+1. 文件名以 `test_` 开头
+2. 测试类继承自 `unittest.TestCase`
+3. 测试方法以 `test_` 开头
+4. 使用 `setUp()` 和 `tearDown()` 方法管理测试状态
+5. 添加清晰的文档字符串说明测试目的
