fix(ci): remove run: steps from scorecard job, guard instant-sync secret

The OpenSSF webapp rejects scorecard results from jobs containing run:
steps. Moved the score-check run: step out of the scorecard job entirely
(the check-critical job already handles policy checks). Pinned actions to
CLAUDE.md standard SHAs. Added secret conditional guard to instant-sync
dispatch job so it skips gracefully when FARM_DISPATCH_TOKEN is absent.
