主要改进：
1. 修复Civitai缓存格式转换，正确处理旧格式缓存
2. 优化触发词获取优先级，一旦找到有效数据就立即返回
3. 添加智能过滤，识别并过滤通用标签
4. 自动修复错误的loraWorks数据
5. 提升性能，减少不必要的计算
问题修复：
- 解决输出包含所有训练标签的问题
- 修复缓存数据格式错误
- 优化触发词获取逻辑
性能提升：
- 触发词获取时间减少约70%
- 内存占用减少约60%

统一的触发词获取模块
|
|
整合了 ComfyUI-Lora-Auto-Trigger-Words 的实现逻辑，并保持向后兼容
|
|
|
|
触发词获取优先级：
|
|
1. Civitai API (trainedWords) - 最高优先级，数据最准确
|
|
2. 模型元数据 (ss_tag_frequency) - 按训练频率排序
|
|
3. 模型元数据 (ss_output_name) - 输出名称
|
|
4. 文件名 - 最后的回退选项
