The role left musicdolphin with an empty venv and a service crash-looping on
ModuleNotFoundError while ansible reported failed=0, because installing the
backend hung off a handler notified by the git checkout:
- the run where the checkout changed failed later on, so handlers never
flushed and the notification was dropped;
- the next run found the checkout already current, notified nothing, and
installed nothing.
Nothing ever converges from there. Make it an ordinary task that runs every
time - uv is fast when there is nothing to do, and its output says whether it
actually installed anything, so a restart is still only notified on a real
change. Give the frontend the same treatment with a cheap stat, since the build
chain has the identical hole and a device with no dist serves no UI.
Also add libjpeg-dev and zlib1g-dev: Raspberry Pi OS has a 32-bit userland,
Pillow publishes no armv7 wheel, and uv therefore builds it from source.
