Ports ZIG/src/os for Linux into ghostty-os: XDG dirs, home dir, hostname, env/PATH helpers, passwd lookup (via nix), shell detection, resources dir discovery, string encodings (printf-q, URL percent), systemd sd_notify, i18n via gettextrs, xdg-open, desktop/cgroup/kernel info, temp dirs, URI parsing (port of std.Uri incl. Ghostty's extra options), and a zbus-based Flatpak HostCommand implementation. The crate stays free of unsafe. Consequences, all tracked as TODO(integration) in docs/rewrite/notes/ghostty-os.md: - locale::ensure_locale is a no-op (setlocale/setenv are unsafe; GTK calls setlocale itself); setenv/unsetenv are not exposed. - passwd's Flatpak branch needs the termio pty and falls back to the sandbox entry for now. - FlatpakHostCommand's D-Bus path is untested (no portal here). Intentional fix: a leading '@' in NOTIFY_SOCKET is treated as an abstract socket. macOS/Windows/WASM modules are out of scope. Test Plan: - cargo test -p ghostty-os (88 tests) - cargo clippy -p ghostty-os --all-targets -- -D warnings
