#   make build-linux        # Cross-compile for Linux x86_64 (glibc)
#   make build-alpine       # Cross-compile for Alpine/musl (fully static)
#   make build-all          # Build all targets
#   make install            # Install to /usr/local/bin
#   make test               # Run all tests
#   make lint               # Clippy + format check
