First step of splitting the runtime dumping ground. Pure directory rename (git mv library/runtime library/kernel) + the six build.zig path references repointed. The module is still named "runtime" for now; the next commits split it into concern modules (ipc, memory, process, time, logging, file-system, ...), dissolve system.zig, and delete the runtime aggregator. The library/kernel name follows the kernel32 model: it is the userspace library that wraps the private kernel ABI, distinct from system/kernel/ (the kernel). zig build green.

//! The root module every user binary is compiled through (build.zig,

//! `addUserBinary`). The program's own file is imported as `program`, and this
|
|
//! shim contributes the declarations Zig resolves from the compilation root —
|
|
//! `main` (dispatched by runtime.start) and the panic handler — and pulls in the
|
|
//! `_start` entry shim. A program therefore only defines `pub fn main`; nothing
