fix(test): accept npm 12 pack --json in packed-consumer

[ScriptedAlchemy]

Summary

• Reuse packOutputFromJson from shared-pack.ts in packed-consumer.test.ts so npm pack --json parsing accepts npm 12's package-keyed object output as well as npm ≤11's array form.
• PR feat(test): packed deleted-source proof level for the consumer harness (#103 stage 4) #225 fixed this pattern at shared-pack.ts, audit-packed-release.mjs, and run-packed-tests.mjs; this file was missed (see Generate an Agent Bundle framework test harness on top of Rstest #103 closing comment).

Test plan

• node scripts/run-packed-tests.mjs packages/agent-bundle/tests/packed-consumer.test.ts (npm 12.0.2)
• pnpm typecheck
• pnpm lint
