Native QR generation for each language's ecosystem: - 27 languages use package manager QR libraries (qrcode, rqrcode, ZXing, etc.) - 10 languages use C FFI to libqrencode (dlopen, ISO_C_BINDING, @cImport, critcl) - 2 shell languages use qrencode CLI (native shell paradigm) - 1 language (Prolog) uses C FFI with CLI fallback Section 9 added to test-sdk.sh with get_qr_file() mapping and QR:unsandbox-qr-ok:ROWS pattern validation across the hydra matrix.
