feat(01-02): scaffold build-logic included build with 5 precompiled plugins

- build-logic/settings.gradle.kts resolves parent catalog via files("../gradle/libs.versions.toml")
- build-logic/build.gradle.kts declares kotlin-dsl + 9 compileOnly asDependency entries
- recipe.quality: Spotless + ktlint + D-11 allWarningsAsErrors safety net (plugins.withId guard)
- recipe.kotlin.multiplatform: D-05 target matrix (androidTarget, iosArm64, iosSimulatorArm64, jvm, wasmJs) + JVM 11/21 split + baseName "ComposeApp" + Koin/Kermit/kotlin-test deps
- recipe.compose.multiplatform: layers on recipe.kotlin.multiplatform (PITFALL #2 avoided) + hot-reload + Compose deps
- recipe.android.application: namespace dev.ulfrx.recipe + findVersion catalog accessor (PITFALL #1)
- recipe.jvm.server: Ktor + Flyway + Postgres with quoted "implementation" configs + cleanDisabled guard
