Extends commands/paste.rs::paste_text with a pre-keystroke check:
if GetForegroundWindow (Windows) / xdotool getactivewindow (Linux
X11) / 'tell System Events ...' (macOS) reports a focused app class
matching KNOWN_TERMINAL_CLASSES, skip the synthesised Ctrl+V and
return an outcome with copied=true, pasted=false, and a user-facing
message ('Terminal detected (kitty) — use Ctrl+Shift+V to insert').
Matches Handy #692: Kitty/Alacritty/Windows Terminal/Codex CLI all
double-insert the transcript when a PTY sees both a synthesised
Ctrl+V and the terminal's own paste hotkey. The terminal list is
ordered most-specific-first so 'windowsterminal' wins over the
generic 'terminal' needle.
Adds classify_terminal() as a pure helper + seven unit tests. The
platform probe (detect_focused_window_class) isolates the fragile
shell-out so the classification rule is test-covered without
needing a real desktop. Wayland doesn't expose a reliable
focused-window API to unprivileged clients, so it conservatively
returns None and the normal paste path runs — consistent with
Kon's Wayland-Pipewire lane.
Prior-clipboard restore (#3) is intentionally skipped when terminal
mode takes over: the user's path to insert the transcript is their
own paste, which needs the transcript on the clipboard.
