feat(dotnet): go-hua/netFramework 迁入并更名 dotnet(.NET Framework 信息)

Browse Source 
- 原包名 netFramework 极易误读为网络框架, 实为读注册表的 .NET Framework
  安装信息, 更名 dotnet; 仅 Windows, 附测试、例程与 README

# dotnet
读取本机 .NET Framework 安装信息（Windows 注册表）：v2/v3/v3.5/v4 各版本
安装状态与版本号，以及 4.5+ 的 release key 换算。
> 迁移自 go-hua/netFramework 并更名：原包名 `netFramework` 极易误读为
> "网络框架"，实为 .NET Framework 信息查询，故更名 `dotnet`。
> **仅 Windows 可用**（读注册表）。
## 用法
```go
import "git.zeroonesoft.cn/golib/zogo/dotnet"
v2, err := dotnet.GetV2Info() // {Install, Version, ServicePack}
v3, err := dotnet.GetV3Info()
v35, err := dotnet.GetV35Info()
v4, err := dotnet.GetV4Info() // {Install, Release, Version}
// release key → "4.8" 之类的展示版本
name := dotnet.CheckFor45PlusVersion(releaseKey)
```
完整可运行例程：[examples/dotnet/main.go](../examples/dotnet/main.go)
## 注意
- 非 Windows 平台调用返回错误（构建不隔离，运行时区分）。
- .NET 5+ 不再写 .NET Framework 的注册表键，本包只覆盖 Framework 系。
