macOS CI / build-and-test (push) Skipped
Serialise PMPrintSettings/PMPageFormat to XML data plus a plist-safe NSPrintInfo dictionary snapshot (PrintTicket), restore via PM*CreateWithDataRepresentation -> PMCopy* -> PMSessionValidate* -> updateFromPM*, and refuse cross-queue replay (R3). PrintPanelService.showProperties now returns PanelCaptureResult; the view model stores tickets in capturedTickets keyed by queue. Also fixes a latent over-release: PMSessionGetCurrentPrinter hands back the session's own printer (borrowed) — the extracted currentPrinterID was PMRelease-ing it, which dangled the session and crashed AppKit's _printerInPrintSession path and session teardown.
