fix(tui): bind whiptail dialogs to controlling terminal
Interactive stage selection did not receive any keyboard input when the setup was started through a pipe (curl ... | bash), because the dialogs inherited the pipe as stdin/stdout and ENTER/SPACE went to the shell. - lib/utils.sh: add has_tty, ensure_term, get_term_size and a run_whiptail wrapper that binds dialog I/O to /dev/tty and returns results via --output-fd 3 - lib/tui.sh: run all dialogs through run_whiptail, add tui_is_available and tui_calc_geometry to clamp dialog geometry to the terminal size - setup.sh: re-attach stdin/stdout to /dev/tty when piped, normalize TERM and use has_tty for the interactive check - install.sh: reconnect stdout as well and normalize TERM before running setup.sh Co-authored-by: Junie <junie@jetbrains.com>
