refactor: improve exception handling in CLI entry points

- Add debug logging when import.meta is not available (CommonJS/Jest environment)
- Only logs when DEBUG environment variable is set to avoid noise
- Addresses SonarCloud code smells about empty catch blocks
- Makes intentional error suppression more explicit
- Helps with troubleshooting when needed
