Add Swift app for iPod contacts and calendar export
Replaces the bash/AppleScript/Python app bundle with a SwiftUI app backed by a testable library target. The app now reads Contacts and EventKit directly rather than sanitizing files someone exported by hand, so the properties that break click-wheel firmware are never written instead of being stripped afterwards: no PHOTO, no X-, no VALARM, no VTIMEZONE, no TZID. Recurring events arrive from EventKit already expanded into occurrences, so no RRULE is emitted either - the open question from the previous version no longer applies. Sanitizing existing .vcf/.ics files is kept as a second path, and gains handling the Python lacked: vCard 2.1 quoted-printable soft line breaks, Apple's item1. property groups, nested STANDARD/DAYLIGHT components inside VTIMEZONE, and UTC times converted to local floating times. Output is laid out as Contacts/ and Calendars/ subfolders mirroring the device, one file per contact and one per calendar. Built via SwiftPM plus Scripts/bundle.sh, which assembles and ad-hoc signs the bundle. Ad-hoc signing is required rather than cosmetic: Contacts and Calendars key permissions off the code signature.
