subsystems - aibox 子系统模块（包）

抽离自 aibox.py 的基础设施子系统，按职责分文件。
当前包含（Wave 1）：
  - executors.py       : CommandExecutor + SubprocessCommandExecutor
  - prompt_manager.py  : PromptManager（单例）
  - db.py              : MemoryDatabase + MemoDatabase
  - skill_manager.py   : SkillManager
Wave 2：
  - conversation_history.py : ConversationHistory（对话历史管理）
  - conversation_compressor.py : ConversationCompressor（对话压缩，注入 llm_client）

依赖方向：common <- subsystems <- aibox
不反向依赖 aibox 任何符号。

采用"重导出"策略：外部统一用 `from subsystems import MemoryDatabase`，
调用点无需关心具体子模块所在文件。
