Overview

This PR runs the Bun and Node consumer fixtures against the packed artifact in CI and before publication, so a broken runtime import or declaration fails the consumer job instead of reaching npm.

Related Issue

Closes #AK-006

Changes

• [MODIFY] .github/workflows/ci.yml
  • Adds a consumer job that packs the SDK and runs the Bun and Node consumer fixtures against the tarball.
• [MODIFY] .github/workflows/publish.yml
  • Runs the same consumer checks after packing and before the publish step, gating publication on their success.
• [ADD] scripts/check-package-consumer.mjs
  • Installs the packed tarball into a clean fixture directory and executes the consumer checks.
• [ADD] fixtures/consumer/package.json
  • Minimal consumer manifest used to install the packed artifact.
• [ADD] fixtures/consumer/verify.mjs
  • Imports the installed package entry points and asserts that runtime exports and declarations resolve.

Verification Results

node scripts/check-package-consumer.mjs

Expected result: the script packs the SDK, installs the tarball into fixtures/consumer, runs verify.mjs under both Bun and Node, and exits 0. Introducing a broken runtime import or a missing declaration causes the script to exit non-zero, which fails the consumer job before publication.

Acceptance Criteria	Status
A broken runtime import or declaration causes the consumer job to fail before publication	✅ Consumer job runs before the publish step and exits non-zero on failure
The pull request includes a reproducible focused check, with its command and expected result documented	✅ node scripts/check-package-consumer.mjs with expected result above

Closes #694
