python: Steady-State Pattern
项目结构：
一个基于Python的珠宝行业企业级稳态系统设计模式(Steady-State Pattern)。系统采用严格分层架构，包含核心层(SteadyStateService基类)、业务服务层(12个具体业务服务)和工具层(ResourceRecycler资源回收器)。主要特点包括：1) 单一职责原则，每个服务仅处理特定业务；2) 通过ServiceManager统一管理服务生命周期；3) 自动资源回收机制，定期清理累积的业务数据；4) 线程安全的服务运行模式。系统涵盖了珠宝行业的完整业务流程(原料采购、设计、生产、质检等12个环节)，通过稳态模式确保长期运行时的资源管理效率。
