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. Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-openagent) Co-authored-by: Sisyphus <[email protected]>

* 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.
