Update GitHub Actions YAML with OIDC permissions and AWS Auth Step Description: Modify the existing .github/workflows file to enable OpenID Connect (OIDC) authentication. This involves updating the job permissions and inserting the standard AWS authentication action to replace the legacy Cirrus logic.

Tasks:

• Locate the target job in the workflow YAML.

• Add the required permissions block to the job:
  YAML
   
  permissions:
  id-token: write
  contents: read
• Insert the aws-actions/configure-aws-credentials step before any build commands.

• Configure the step to accept role-to-assume (we will use a variable reference here, e.g., ${{ secrets.AWS_ROLE_ARN }}{}).

Acceptance Criteria:

• [ ] Workflow syntax is valid and passes linting.

• [ ] The permissions block is correctly correctly positioned at the job level.

• [ ] The aws-actions/configure-aws-credentials step is present in the execution order.
