feat: 平台规则中心完善 - TDD开发完成

Phase 1: 编写30个测试用例 (RED阶段)
- test_rule_validator.py (10个测试)
- test_sensitive_filter.py (5个测试)
- test_seo_optimizer.py (5个测试)
- test_html_generator.py (5个测试)
- test_content_pipeline.py (5个测试)

Phase 2: 实现5个核心服务 (GREEN阶段)
- RuleValidator: 规则校验服务（标题/内容/AI模式检测）
- SensitiveFilter: 敏感词过滤服务（政治/医疗/金融/低俗）
- SEOOptimizer: SEO优化服务（关键词密度/位置优化）
- HTMLGenerator: HTML生成服务（平台适配HTML/Markdown/纯文本）
- ContentPipeline: Pipeline编排服务（校验→过滤→优化→生成）

Phase 3: 前端集成
- 内容编辑器集成平台选择器
- 规则校验和优化功能
- 多格式复制功能

Phase 4: 文档更新
- 待办事项文档更新
- 标记平台规则中心为已完成
