# cellar-cli-c — reimplementazione C del client CLI di Cellar
#
# Target principali:
#   make            -> dist/cellar-cli          (x86-64 statico, glibc)
#   make 32         -> dist/cellar-cli-i686     (i686 statico, per sistemi 32 bit)
#   make arm64      -> dist/cellar-cli-aarch64  (aarch64 statico via cross toolchain)
#   make dist       -> tutti e tre
#   make verify     -> controlla dipendenze, simboli GLIBC richiesti, ldd, size
#   make test       -> parity test contro il client Python (server mock incluso)
#   make asan       -> build dinamica con AddressSanitizer/UBSan per i test
