// Establishes the D-05 target matrix + JVM toolchain + warning policy.
// Android bytecode is JVM 11 (D-08); server + desktop + shared/jvm are JVM 21.
//
// This plugin is intentionally dependency-free: shared/ must stay light
// (no Koin, no Kermit), and composeApp adds those in its own build file.

// matching KLIB unique_names. This is an upstream Compose-Multiplatform 1.10 +
// lifecycle 2.10 ecosystem condition (KT-62515-style), not actionable in our
// source — so we keep -Werror on real source compilation tasks but disable it
// for the metadata-aggregation step where no user code is being compiled.
