fix: complete comment-based help in scaffold function

Add missing .INPUTS and .OUTPUTS sections required by the PowerShell
functions standard. Clarify .SYNOPSIS/.DESCRIPTION (they were identical
and said 'performs tests' when the function actually greets). Fix the
.EXAMPLE output (remove spurious quotes around the output string).
