GraalVM native-image requires a C compiler (gcc) and zlib dev
headers to compile native binaries. The maven:3.9.6-eclipse-temurin-21
image is JDK-only and lacks these build tools, causing the build
to fail with:
Error: Default native-compiler executable 'gcc' not found via PATH
Extend the install step with build-essential (gcc, g++, make)
and zlib1g-dev so the native-image pipeline has the required
toolchain.
