Add labs: 59 Python lab scripts + tools + run_lab.sh

- labs/src/: 59 lab scripts covering OA API (Ch2-Ch25 + extras)
  - All C++ references removed, oapy-only documentation
- labs/tools/: debug and test utilities
- labs/run_lab.sh: lab runner with LD_PRELOAD and env setup

+Lab 13-3: OccTraverser — Occurrence Traversal
+Creates a custom occurrence traverser by subclassing oaOccTraverser.
+The traverser walks through the occurrence domain hierarchy.

+
+This lab demonstrates:
+  - Subclassing oaOccTraverser to override virtual methods
+  - Overriding processOccurrence, processInst, processNet
+  - Controlling traversal with startInst/endInst
+  - Using default pre-order and post-order traversal patterns
+
+Note: The oapy bindings do not have Python director support for virtual

+pattern of creating the hierarchy and using calcVMSize.

+Lab 18-6: Pcell CPP — Python 转换版
+=====================================
+
+本 Lab 演示 OpenAccess Pcell (Parameterized Cell) 的完整工作流程：
+  1. 首次运行 (CreateDesigns):
+     - 创建 top 和 pc 两个 Design
+     - 注册 IPcell 生成器 (Python 子类实现，替代原生 IPcellCPPDefMgr)
+     - 定义 SuperMaster (defineSuperMaster)
+     - 实例化 Pcell 并触发 onEval → genPcell 回调
+     - 保存设计到磁盘
+  2. 二次运行 (ReadDesigns):
+     - 从磁盘读取已有设计
+     - 演示 Pcell 的 SubMaster 读取和评估流程
+     - 验证 PcellDef 数据完整性
+  3. 观察者模式:
+     - oaPcellObserver: 监控 Pcell 评估前/后事件
+     - oaDesignObserver: 监控 Design 首次打开和清理事件
+
+运行方式:  ./run_lab.sh lab18_6_pccpp.py

+oapy Lab 2-1: mdparies — LEF/DEF 导入导出工作流

+  1. lef2oa   — 将 LEF 文件导入 OA 库（生成 techLib + 标准单元 abstract views）
+  2. def2oa   — 将 DEF 文件导入 OA 库（生成完整 layout 设计）
+  3. oa2def   — 从 OA 设计导出 DEF 文件
+  4. oa2lef   — 从 OA 库导出 LEF 文件（指定 cell）
+  5. oa2strm  — 从 OA 设计导出 GDSII 流文件
+  6. oa2verilog — 从 OA 设计导出 Verilog 网表
