Migration ticket: UIKit/XIB/MVP → SwiftUI

[zigdanis]

What

Adds migrations/02-swiftui.md — a self-contained agent prompt to migrate the UIKit scene layer (XIB-backed View ↔ Presenter ↔ Configurator triples) to SwiftUI with observable view models.

This PR carries the ticket/prompt only; it does not implement the migration. Hand the prompt to an agent to produce a plan and then implement it.

Why

The UI is UIKit + XIBs/storyboards with hand-wired MVP/Clean scaffolding (Presenters, Configurators, Routers). SwiftUI removes most of that boilerplate while the Core business-logic framework stays intact and reused.

Scope (per the prompt)

• Leaf-first scene migration: EmptyPerson → PersonOverview → EditPerson → PersonsList
• Presenters → @Observable view models calling existing Core use cases
• NavigationStack routing; PhotosPicker replacing WDImagePicker
• TimelineView for live age via AgeCalculator
• Keep Core tests green; update README architecture section

📝 Walkthrough

Walkthrough

This PR introduces a migration specification document (migrations/02-swiftui.md) that defines a scene-by-scene plan to convert the GrowingUp app's UIKit interface layer (XIB files and storyboards) to SwiftUI, while preserving existing Core logic, App Group data sharing, and localization support. The plan maps UIKit presenters to SwiftUI observable view models and specifies requirements for navigation, photo handling, and live age updates.

Changes

UIKit-to-SwiftUI Migration Specification

Layer / File(s)	Summary

Poem

🐰 A blueprint for transitions fair,
From XIB files floating in the air—
SwiftUI awaits with observable grace,
Core logic steady in its place.
Hop by scene, we'll make it bright! ✨
