the documented way to use this did not work

`import qs.horologion.modules` was the README's headline instruction and it
fails outright: Quickshell resolves `qs` against the host config root, not
the subtree, so in an empty shell the type is unavailable and in a populated
one the widget would have silently bound to the host's Config and Theme
instead of its own. The imports inside are now relative and each directory
carries a qmldir, so `import "horologion/modules"` works in any host and the
three pieces really are usable on their own.

  - refresh() dropped a request made while a run was in flight, so a
    jurisdiction or date set a moment after startup never took effect until
    midnight. It queues now.
  - The waybar script exited non-zero on its error paths, and waybar hides a
    module whose script does that -- so a missing typikon made the module
    vanish rather than say so, and the .error CSS was dead. An unrecognised
    --format field raised instead of rendering empty, and the tooltip
    interpolated unescaped text into Pango markup, which matters because
    --update-menaion fetches commemorations from a page nobody here controls.
  - The installer aborted the whole run at the point where it printed
    'leaving it alone', and a wholly successful run exited 1 because the last
    statement was a failed [ -d ] test under set -e. --help demanded typikon,
    which is what --help would have told you to install.
  - eww painted every day with the feast colour and printed a dangling
    separator, because it compares against "" and eww renders a JSON null as
    the string "null". The parenthesised ?: form two lines away was already
    right. The week list also repeated today.

pip install typikon installed nothing; there is no such package, and that was
the first line of every install path. Pascha now carries its label instead of
being a bare ISO date in a corner.

tests/smoke.sh covers the scripts, which is where all of this lived and where
nothing was covered. It caught two of these while being written.
