Keep the useful feature work from the OpenAuthenticode comparison on psign-native surfaces instead of exporting compatibility command clones. Add PE signature clearing, PE append signing, extensionless PE detection, .psc1 clear support, and initial SignedCms projection through existing psign cmdlets.

Make portable PE signing replace existing embedded signatures by default and reserve append behavior for --append-signature (/as), matching SignTool semantics across native-shaped portable signing, portable sign-pe, and code PE signing. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Add regression coverage for SignTool-compatible replace-by-default behavior through the PowerShell Set-PsignSignature surface and psign-tool code signing. Existing psign-tool portable sign-pe and native-shaped portable sign tests cover append opt-in with --append-signature. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
