Feature Request
Acceptance Criteria
- Compare current installed version with latest npm version on each CLI invocation
- Display a notice when a newer version is available (e.g.,
Update available: 1.2.3 → 1.3.0. Run npm update -g @aws/agentcore-cli to update.) - Notification is non-blocking and does not interrupt normal CLI operation
- Cache the version check result to avoid slowing down every invocation (e.g., check at most once per 24 hours)
