## 问题根因
MaterialMatchingService中直接调用material_repo.get_by_project_id()方法，
该方法只返回素材基本信息，不包含segments字段，导致：
1. material.segments.is_empty()始终为true
2. 匹配逻辑创建虚拟片段，使用原始素材完整时长
3. 10.042秒的原始素材与1.267秒的模板片段比较，超出692.8%

## 解决方案
将所有调用material_repo.get_by_project_id()的地方改为：
MaterialService::get_project_materials()

该方法会：
1. 调用repository.get_by_project_id()获取素材基本信息
2. 为每个素材调用repository.get_segments()加载片段信息
3. 返回包含完整片段信息的素材列表

## 修改位置
1. match_materials方法 - 主要匹配逻辑
2. can_template_be_fully_matched方法 - 模板匹配检查
3. match_materials_with_used_segments方法 - 批量匹配逻辑

## 预期效果
- material.segments不再为空
- 匹配逻辑使用真实的切分片段而不是虚拟片段
- 片段时长将是合理的切分后时长（如1-5秒）而不是原始素材时长
- 时长匹配评分将更加准确

这是一个关键修复，解决了匹配逻辑的根本问题。
