feat: v1.1.0 — 上下文引擎重构 + 技能系统升级 + SOUL.md 支持

- 版本号更新: 1.0.0 → 1.1.0，全量同步 package.json/lock/README/docs/UI
- 上下文长度自动检测: 切换模型时从 model_info 读取实际 context_length
- SOUL.md 支持: 每次发送自动扫描工作空间 SOUL.md，注入为首条 system 消息且不可压缩
- 系统提示词卡片: AI 回复顶部可折叠展示实际发送给模型的完整 system prompt
- Token 校准: 利用 Ollama 返回的实际计数动态修正估算器(EMA)
- 消息重要性评分: 纯规则打分，trim/summarize 按重要性而非时间顺序
- 结构化压缩: LLM 压缩输出 JSON 格式(topics/decisions/pendingTasks/constraints)
- 技能系统 v1.1: 语义匹配(embedding) + 参数自优化 + 未使用衰减 + 技能链合并
- 修复: 100+ TypeScript strict 模式编译错误清零
