huntedbytheirsandSisyphus aca40a69b0 Add public headers
Declarations for the string core, stdio, stdlib, unistd, errno, sys/types, and the raw syscall interface; the FILE layout stays private in src/internal.h.

/*
* stdio.h — standard I/O for nulsl-libc.
*
* Minimal for now: unbuffered writes to a file descriptor, plus ENOSYS
* stubs for the buffered/formatting machinery that is still to come.
* A FILE is just a file descriptor until we grow a real buffering layer.
