refactor(core): add verbose config, improve module lookup, fix is_valid_url

- Add verbose config option to control CNR fetch logging
- Improve get_module_name with cnr_id/aux_id fallback via repo_cnr_map
- Fix is_valid_url misuse of try/finally that could cause runtime errors
- Move SSH_URL_PATTERN to module-level constant for performance
