Ports the parts of Ghostty's IO layer that don't depend on the terminal: - pty.zig: pty pair, window size, mode, child-side setsid/TIOCSCTTY; master is CLOEXEC with IUTF8 set - Command.zig: fork/execvpe with Ghostty's exact child setup (stdio dup2, best-effort chdir, rlimit restore, os/runtime pre-exec hooks, cgroup handling) and exit status decoding - shell_integration.zig for bash/zsh/fish/elvish/nushell plus feature flags; scripts copied verbatim to resources/shell-integration/ - terminfo generator for xterm-ghostty, byte-identical to Zig's encode output (golden file produced with the real Zig code) This crate opts into unsafe_code = "deny" (fork/exec need it) with allow + SAFETY comments on minimal items. Integration left: config-derived option types are local stand-ins; cgroup D-Bus scope creation is a closure hook; Exec/Termio/Thread/ stream_handler wait for ghostty-terminal. Pty now closes both fds on drop (Zig never auto-closed the slave) - to re-check when wiring Exec. Test Plan: - cargo test -p ghostty-termio (52 tests, incl. real pty spawn test expecting "hi\r\n31 97\r\n" from `echo hi; stty size`)
