refactor(01-03): apply recipe.* conventions to composeApp + shared, drop js

- composeApp/build.gradle.kts now applies 4 recipe.* IDs (kotlin.multiplatform, compose.multiplatform, android.application, quality); removes all structural target/android/nativeDistributions blocks (114 -> 28 lines)
- shared/build.gradle.kts applies recipe.kotlin.multiplatform + recipe.quality + androidLibrary; adds explicitApi() (D-12) and KotlinNativeTarget/Framework baseName = "Shared" override (D-07 / PITFALL #10); keeps android { } block per Open Question #1
- Adds libs.koin.android to androidMain dependencies (for Plan 04's MainApplication androidContext)
- Drops js target per D-01: removes js { browser() } from both modules and deletes shared/src/jsMain/Platform.js.kt
- iosX64 remains absent per D-02
- No version literals leak; tools/verify-no-version-literals.sh + verify-shared-pure.sh both pass
