Finder hands files to an app as an Apple event, not on the command
line. winit doesn't handle it, so AppKit answered "PrintCraft cannot
open files in the PDF document format". The bundle also declared no PDF
document type: its Info.plist still carried the sibling image editor's
types.
- Info.plist declares PDF (by extension and MIME type) as a document
type, role Editor, rank Alternate: offered under Open With and
settable as the default, without taking over on install.
- apps/printcraft registers open-documents and quit Apple event
handlers through fmv-macos-events (=0.1.0, the audited safe wrapper
PhotoCraft uses, since the Objective-C interop needs unsafe), before
the launch event arrives.
- printcraft-ui-egui gains OsEvent and PrintCraftApp::os_events, polled
every frame: Open opens each file as File > Open does; Quit closes the
window like its close button, so unsaved changes are asked about.
