chore(main): release 5.0.0

[github-actions]

🤖 I have created a release beep boop

5.0.0 (2026-06-25)

⚠ BREAKING CHANGES

• iam: infrastructure/aws/iam/ecr no longer creates the build workflow user, access key or group, and no longer outputs build_workflow_access_key_id / build_workflow_access_key_secret. Consumers must instantiate the new build-user module, pass its group_name to ecr (new required input build_workflow_group_name) and to s3-assets, take the build credentials from build-user outputs, and run a tofu state mv to preserve the existing user and access key (see infrastructure/aws/iam/build-user/README.md). The IAM group is renamed from ecr-managers to asset-publishers (recreated; does not rotate the user's keys).

Features

• iam: separate build workflow user from asset repositories + add S3 asset support (#402) (9ae9e09)
