/**
* Model-facing result rendering for the pwsh tool — the PowerShell twin of
* `dsh-tool-bash`'s renderer minus the sandbox surface: stdout, a marked
* stderr section, truncation notices with spill paths, then exit-status
* markers. Non-zero exits are reported, not errored — the model decides how to
* react; only infrastructure failures (spawn errors, aborts) surface as
* isError results.
