Component Registration Debugging (JavaScript) +- New debug options in `ReactOnRails.setOptions()`: + - `debugMode` - Full debug logging + - `logComponentRegistration` - Component registration details +- Logging includes: + - Component names being registered + - Registration timing (performance metrics) + - Component sizes (approximate) + - Registration success confirmations + +### 4. Helper Module Updates (`lib/react_on_rails/helper.rb`) +- Integrated SmartError for auto-loaded bundle errors +- Required smart_error module + +### 5.
