Use run during the creative loop, check for fast language feedback, and build when you need the actual executable.

```yh
.\tools\yeho.ps1 new console <path> <name>
.\tools\yeho.ps1 check <path>
.\tools\yeho.ps1 run <path>
.\tools\yeho.ps1 build <path>
```


## PowerShell

Use run during the creative loop, check for fast language feedback, and build when you need the actual executable.

Verification: command reference

```powershell
.\tools\yeho.ps1 new console .\hello hello.app
.\tools\yeho.ps1 check .\hello
.\tools\yeho.ps1 run .\hello
.\tools\yeho.ps1 build .\hello
```


The current promoted product target is Windows x64.

Product builds lower through Forge and Kyber rather than generating C++.
