feat: add Github star call-to-action after successful scans (#17)

- Display friendly message in table format after scan completion
- Message only shown for table output, respects --quiet flag
- Works for both regular and cloud scans
- Encourages users to star repository on GitHub

Tests:
- Added 3 new test cases for star message display
- Verified message appears in table format
- Verified message is suppressed in quiet mode
- Verified message doesn't appear in JSON/CycloneDX formats"
