Subject: [PATCH] feat(01-04): add Koin + Kermit bootstrap commonMain + iOS
 bridge
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add initKoin(config) helper wrapping startKoin { modules(appModule) } (PITFALL #4 single entry)
- Add empty appModule placeholder (D-14) — Phase 2+ extends
- Add configureLogging() setting Kermit tag "recipe" (D-15)
- Add iosMain doInitKoin() bridge — Swift-accessible as KoinIosKt.doInitKoin()
- configureLogging() always runs before initKoin() so module loading can log
