Ports the remainder of ZIG/src/termio: Options, backend, message, mailbox, Termio, Thread, Exec and stream_handler. Threading model (replacing libxev): the IO thread owns Termio and runs a single poll(2) loop over the mailbox eventfd, a stop eventfd, the child pidfd and pty POLLOUT, driving Ghostty's timers (25 ms resize coalescing, 1 s synchronized-output, 15 ms selection scroll, 200 ms termios polling). A separate pty read thread locks the shared renderer state and feeds the terminal. Renderer and surface interaction go through RendererMailbox/SurfaceMailbox traits. The stream handler answers all queries (DA, DSR, XTVERSION, DECRQM, OSC color queries, XTGETTCAP, DECRQSS, ...) and forwards titles, pwd, OSC 52, notifications, progress and bell as surface messages. Zig unlocks the renderer mutex when a mailbox is full; here overflow goes to an ordered outbox flushed after the locks drop. IO1's local stand-ins are replaced with the real config types. Open: RendererState lives in termio for now (renderer State.zig is being ported); kitty graphics replies and tmux viewer are not hooked up; wait-after-command lives in Surface (core); Flatpak stop path needs a ghostty-os change. Test Plan: - cargo test -p ghostty-termio (102 unit + 21 end-to-end tests on a real pty, incl. backpressure, DA1 replies, resize coalescing, exits)
