fix(intelligence): 精确化 dead_code 标注并实现 LLM 上下文压缩

- 将 intelligence/llm/memory/browser 模块的 dead_code 注释从模糊的
  "reserved for future" 改为明确说明 Tauri invoke_handler 运行时注册机制
- 为 identity.rs 中 3 个真正未使用的方法添加 #[allow(dead_code)]
- 实现 compactor use_llm: true 功能：新增 compact_with_llm 方法和
  compactor_compact_llm Tauri 命令，支持 LLM 驱动的对话摘要生成
- 将 pipeline_commands.rs 中 40+ 处 println!/eprintln! 调试输出替换为
  tracing::debug!/warn!/error! 结构化日志
- 移除 intelligence/mod.rs 中不必要的 #[allow(unused_imports)]
