ci: keep smoke canaries out of the status file so zero PASS can turn red

canary-skip and canary-sidecar appended SKIP and PASS records to the same
JSONL summarize.py reads for shipped examples, so every run carried at least
one PASS and the documented 'zero PASS is red' guard could never fire. Both
now run with --no-record, like the inverted canaries, and grep their own
[SKIP]/[PASS] verdict.

Closes #536
