feat: 集成 waveform_trace 波形调试工具

新增功能：
- waveformTracer.ts: 调用 waveform_trace.exe 的工具实现
- toolExecutor.ts: 添加 waveform_trace 工具分发
- types/api.ts: 添加 WaveformTraceArgs 类型定义

工具源码 (tools/waveform_trace/src/):
- AST 解析 + BFS 信号追踪
- VCD 波形解析
- 修复通用 testbench 支持

配置文件：
- .gitignore: 排除 exe 和打包产物
- .vscodeignore: 发布时排除源码
- build.bat/build.sh: 打包脚本

tools/waveform_trace/src/graph_builder.py
