setup-plan.sh prints 'Copied plan template to $IMPL_PLAN' after copying the template (to stderr in --json mode, stdout otherwise), but the PowerShell twin emitted nothing on the successful-copy path -- only the 'Plan already exists' skip message and the 'Plan template not found' warning existed. So the two scripts had a divergent status-output contract on a fresh run.
Emit the same message after WriteAllText, routed like the sibling skip message ([Console]::Error.WriteLine in -Json so stdout stays pure JSON, Write-Output in text mode). Mirrors the bash wording and stream routing exactly.
