//! danos user-space runtime library — a nascent libc. Every user binary (init,
//! and later the VFS server + device drivers) imports this as `@import("rt")`:
//! syscall wrappers, the C-convention heap, IPC helpers, and the process start
//! shim. It is compiled into each binary (inheriting its `.large` code model and
//! freestanding target), so all user programs share one implementation.
//!
//! A user binary needs three lines:
//!   const rt = @import("rt");
//!   pub const panic = rt.panic;
//!   comptime { _ = &rt.start._start; }   // pull the entry shim in
//! and a `pub fn main() void`.
