v2.2.1
fix: cross-compile NIF by placing .o in PRIV_DIR Move the object file from c_src/ to PRIV_DIR so each cross-compile target gets its own .o file. Without this, the x86_64 .o persists and the aarch64 linker fails with "Relocations in generic ELF (EM: 62)". Also add make_clean to mix.exs for belt-and-suspenders cleanup.
