In host-mode the ui-test job runs as root, so vite (test:pwa),
svelte-kit and Playwright write build/, .svelte-kit/, test-results/ and
playwright-report/ root-owned into the shared host workspace. The
act_runner (non-root) then cannot remove them at teardown
("unlinkat ui/frontend/build: permission denied"), which spuriously
marks this or a sibling job that inherits the dirty workspace as failed
— it hit go-unit on the #83 merge even though every test passed.
Add an `if: always()` step that removes those generated dirs while the
job still has root, after the artifact uploads. Keeps the shared
workspace clean for the runner's own teardown and for later jobs.
