V31 Gate 1: Align V30 canonical artifact test

Update the demonstration specifying test to expect the promoted V30 canonical input artifact count now that V30 carries the V21-like generated artifact quartet.

Proof: node --test --test-force-exit --test-concurrency=1 protocol-demonstration/test/v21-specifying.test.js; node scripts/check-bitcode-canonical-inputs.mjs --current-target V30; pnpm run check:v31-gate1; git diff --check.
