ldd on the built binary shows only libz.so.1 is missing from distroless/cc-debian11; libssl/libcrypto are statically linked by this build and do not need to be copied. libstdc++.so.6 and libgcc_s.so.1 are already present in the distroless/cc variant. Also consolidates the mv + mkdir into a single RUN layer. Co-Authored-By: Claude Sonnet 4 <noreply@anthropic.com>
