Subject: Initial scaffold: Makefile, stub malloc/free/realloc, test harness

Build system produces libft_malloc_$HOSTTYPE.so shared library with
Libft (NOMALLOC=1) as dependency. Stub functions print their name
and return NULL. Test runner compares system malloc vs LD_PRELOAD
output using write(2) to avoid stdio interference.
