feat: Phase 3 世界书引擎移植 + EJS 支持

- 新增 task-worldinfo.js: 从 EW 移植世界书激活/分桶引擎
- 新增 task-ejs.js: 从 EW 移植 EJS 模板渲染引擎
- 新增 vendor/ejs.js: EJS runtime vendor
- prompt-builder.js: 改为异步, 接入 worldInfoBefore/After/atDepth
- prompt-profiles.js: 新增内置块 charDescription/userPersona/worldInfoBefore/After
- 更新 extractor/retriever/compressor/consolidator 接入新 builder
- st-context.js: 扩展 ST 上下文字段兜底
- 新增 tests/task-worldinfo.mjs: 世界书引擎测试
