Add logMessage, getBreadcrumbs, and enableDebugLogging features

- Add logMessage(level, title, message?, data?) for structured logging with title
- Add logMessageAsync() async variant
- Add getBreadcrumbs() public method to retrieve current breadcrumbs
- Add static enableDebugLogging field for global debug output control
- Update all debug logging to respect the global debug flag
