exec_cli runs cmd.exe on Windows despite PowerShell-first design #7
Description
The server ships src/utils/powerShellSession.ts and every other Windows codepath is PowerShell, but exec_cli shells out through cmd.exe.
Repro
exec_cli("node -v; git rev-parse HEAD") -> "node: bad option: -v;"
exec_cli("echo %COMSPEC%") -> C:\WINDOWS\system32\cmd.exe
exec_cli("echo shell=$env:ComSpec") -> literal, unexpanded
Impact
; chaining, $env:, object pipelines, and every PowerShell idiom fail. Agents reasonably assume PowerShell given the rest of the server, and the tool description says nothing about cmd.
Fix
Route Windows exec_cli through PowerShell by default, with an explicit opt-out (shell: "cmd" | "powershell") for callers that need cmd semantics. Document the default in the tool description.
