      <!-- ── CLI bundling (rendered by `udb sdk generate`) ─────────────────────
           Installing/building this SDK also yields the version-matched `udb`
           CLI. dev.udb.cli.Launcher locates an installed `udb` (matching
           v${project.version}) or downloads the pinned GitHub release binary and
           execs it. The assembly plugin produces an executable, dependency-fat
           jar (`udb-cli`); appassembler emits a thin `udb` wrapper script under
           target/appassembler/bin so `mvn package` then `target/appassembler/bin/udb …`
           works without remembering the main class. Both are additive: they do
           not change the library jar or its coordinates. -->
