feat(install): always hand the output to the steps window

The appearance panel is the usual way a scheme gets applied, so the hints
install.sh prints belong on screen whoever calls it, not only when the
panel pipes them. install.sh reruns itself as a child, tees the output to
the terminal and a temporary log, and passes the log to udt-steps install,
keeping the child's exit status.

With the window as its main reader, the output is now a summary: only
udt-palette's count line rather than all 86 generated paths, and a restart
hint in place of the closing ls -l dump.
