Subject: [PATCH] clj-kondo: fix startup crash with GraalVM >= 25.1

GraalVM 25.1 removed @AutomaticFeature discovery, so the bundled
graal-build-time feature stopped running. Register it explicitly; drop
when clj-kondo/clj-kondo#2949 ships. Add versionCheckHook so a binary
that cannot start fails the build.

Assisted-by: Claude Code (claude-fable-5)
