Type `yo <what you want>` at your PowerShell prompt and the suggested command is
prefilled on your next line -- ready to run, edit, or cancel -- or you get a printed
answer. A native Go binary plus a small PowerShell integration; an acknowledged
GPLv3 derivative of yoshell (pizlonator/yosh).
After installing, run `yo --setup` to wire your $PROFILE, check PSReadLine, and set
an API key (ANTHROPIC_API_KEY or OPENAI_API_KEY) -- winget only puts yo.exe on PATH.
