v0.5.2

v0.5.2 — republish v0.5.1 code

No source change. v0.5.1 tag on remote points at an incomplete
intermediate commit (638687a) that was missing the touch_events /
touch_count smc work + tests; the complete code is at 53f1ecf on
main but never got tagged because the second tag attempt aborted
on "tag already exists".

v0.5.2 tags main at the complete code so the CI-published Docker
image matches the v0.5.1 changelog entry. Pin consumers to
psyb0t/wickworks:v0.5.2.
