feat(01-04): wire JVM + Wasm main + Swift iOSApp to bootstrap Koin + Kermit

- Desktop main() calls configureLogging() → initKoin() before application { Window { App() } }
- Wasm main() calls configureLogging() → initKoin() before ComposeViewport { App() } (PITFALL #8 future-proof)
- iOSApp.swift imports ComposeApp and calls KoinIosKt.doInitKoin() in init() — single iOS call site (PITFALL #4)
- MainViewController.kt and App.kt unmodified (anti-pattern guards)
