Pull Request Overview

This PR extends the CLI’s region support by adding the new AWS-AU region everywhere it’s used: configuration commands, helper utilities, integration tests, and documentation.

• Added AWS-AU (and related GCP-EU/GCP-NA) entries to region handler, interactive prompts, config mappings, and personalize endpoints.
• Refactored integration tests to import a centralized REGION_MAP and initialize new regions.
• Bumped package versions, updated README usage examples, and cleaned up test stubs.

• The code still accepts plain 'AU' in the region handler but the interactive choices no longer include {name: 'AU', value: 'AU'}. For consistency, either add the plain 'AU' choice here or remove support for 'AU' in the handler.
