chore: bump Claude Code to 2.1.321 and Agent SDK to 0.3.321

* release: push tags with the release deploy key

So the tag ruleset (terraform-config#81310) can be enforced: GITHUB_TOKEN can never bypass a ruleset, a deploy key can. No change to how releases are cut.

* release: SHA-pin actions/checkout in the deploy-key jobs

The checkout steps now hold the ruleset-bypass deploy key, so resolve actions/checkout by full SHA (v6.0.2, same pin as sync-base-action.yml) rather than the mutable v6 tag.
