fix: add missing Pinocchio CI badge to README

Add a scheduled-run badge for the Pinocchio workflow, which has been
active for months (286 runs, 13 example projects) but was missing from
the README. Keeps the existing ?event=schedule filter so badges reflect
daily scheduled CI status rather than individual push/PR runs.
