Improve method naming and warning message clarity

- Rename supports_auto_registration? to supports_autobundling? for consistency with auto_load_bundle config
- Improve system checker warning message to be more descriptive about nested_entries requirement
- Update all references in tests and configuration files
- Remove redundant ModuleLength disable directive (auto-fixed by RuboCop)
