Fix RuboCop workflow issues and warnings (#1810)

## Issues Fixed:
1. **Eliminated suggestion warnings**: Added SuggestExtensions: false to disable
   rubocop-capybara/factory_bot/rspec_rails suggestions
2. **Ruby 3.5+ compatibility**: Added benchmark, logger, ostruct gems to silence
   deprecation warnings about gems moving out of stdlib
3. **Cleaner RuboCop output**: No more tip messages or warnings during execution

## Changes:
- Updated .rubocop.yml: Added SuggestExtensions: false
- Updated Gemfile.development_dependencies: Added benchmark, logger, ostruct gems
- All RuboCop checks pass cleanly without warnings
- All existing tests continue to pass

## Benefits:
- ✅ Clean RuboCop execution without distracting warnings
- ✅ Forward compatibility with Ruby 3.5+
- ✅ Better developer experience during linting
- ✅ Maintains all existing functionality and test coverage
