Take the install back, and pull the next one in

install.sh has been the only half of its job that was written down. Removing
Dikte meant remembering a symlink, three desktop files, an autostart entry and
a handful of kglobalshortcutsrc keys, and updating meant a pull followed by
guessing which of those the new version had moved. Both are now scripts,
because both are lists somebody would otherwise keep in their head.

uninstall.sh removes what install.sh put down and stops there. What you have
written is yours: the settings and the dictations, the meetings and the
recordings survive a plain run, and --purge is the word that deletes them. It
prints what that would cost first, how many dictations, how many meetings, how
much audio, since a count is the thing that makes the sentence real, and
without a terminal to ask it refuses rather than assuming --yes. Only our own
symlink goes; a file of that name somebody else put there is left alone. The
shortcuts are handed back to `dikte shortcut remove` rather than unpicked from
KDE's file here, because that is the half that knows whether they went into
kglobalshortcutsrc or into GNOME's gsettings.

update.sh asks whether anything is waiting before it complains about anything
else, because an unfinished afternoon in the working tree is nobody's problem
on a day when nothing has been published. If something is waiting and you do
have edits of your own, it stops and says so rather than choosing for you. The
merge is --ff-only: an update is somebody else's commits arriving, never a
merge a script decided to make on your behalf.

Then install.sh runs again, since an update can add a dependency or move a
file, and it is told which keys you chose so that it puts those back instead of
its own defaults. They are read from the settings rather than from the
desktop's file, that being the one place they mean the same thing on KDE and on
GNOME, and a key you had turned off is passed back as the empty string rather
than quietly becoming the default again. Finally the running instance is
restarted, because it is still holding the code from before the pull.
