- 更新 README.md 中的项目结构说明
- 添加 pprof 性能分析工具的使用说明
- 更新 build.bat 文件,增加 proto 文件编译命令
- 升级 go-logr/logr 依赖至 v1.3.0
- 降级 go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc 依赖至 v1.16.0
- 降级 go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp 依赖至 v1.16.0
- 升级 go.opentelemetry.io/otel/trace 依赖至 v1.20.0
- 移除 logic/main.go 中的冗余代码
- 重构 logic/server.go 中的 Start 函数
- 更新 login/main.go 文件
