fix(ci): resolve OpenSSF Scorecard workflow failures

- Set publish_results: false on the Run Scorecard step to remove the
  dependency on the public Sigstore transparency-log signing step,
  which is failing upstream with "tuf: invalid key".
- Add continue-on-error: true to the Run Scorecard step so a
  transient GitHub code-search rate-limit (429) on the OSS-Fuzz
  integration check no longer reddens this repo's CI. Honest
  soft-fail, not a fake green; matches the gating pattern in
  mizcausevic-dev/kineticgain-com-apex commit 2cc1eba.
