chore(microvm): build and publish lifecycle hook

[edersonbrilhante]

Description

Add CI and release automation for the MicroVM lifecycle hook introduced by #5280. The hook is registered as a Yarn workspace, built and tested in the Lambda workflow, packaged as a release asset, and attested alongside the Lambda artifacts.

The release workflow uploads microvm-lifecycle-hooks.zip and its attestation assets. The storage adapter is aligned with the current storage-provider export API so the new build succeeds on the #5280 base.

Test Plan

• yarn install --immutable --mode=skip-build
• yarn prettier --check "services/microvm-lifecycle-hooks/**/*.{ts,json,md}"
• yarn eslint services/microvm-lifecycle-hooks/src
• NX_DAEMON=false yarn nx test @aws-github-runner/microvm-lifecycle-hooks (45 tests passed)
• yarn workspace @aws-github-runner/microvm-lifecycle-hooks build
• Packaged and inspected microvm-lifecycle-hooks.zip
• YAML parsing and git diff --check
