- 修复 nodes 中 llm 导入路径错误 (../../services/llm -> ../../../services/llm)
- 修复动态导入缺少 .js 扩展名 (./index -> ./index.js)
- 修复 bookStore.update 支持 title/bookScale 字段
- 修复 fillAiResultsAsync 参数类型 (number -> string)
- 修复 plan.node.ts ChatMessage 类型注解
- 修复 outline.parser.ts recommendSubsections 字段
- 修复 tts.service.ts splitByEnglishSentence 未定义问题
- 修复 llm/index.ts listAll -> listEnabled
