closes #137 - right arrow consumed the escape sequence without forwarding it, so the cursor couldn't move back right after moving left (60149a2) - p10k's instant prompt redirects stdout to a temp file that exec iris inherits, sending the overlay there instead of the terminal and looking like a dead keyboard. Reopens /dev/tty when stdout isn't a terminal (7ebbb0c) - zsh/bash autostart lacked the interactivity check fish already had, so agentic tools sourcing your rc file spawned a rogue iris that seized /dev/tty (5fe58be)
