AirHotReload class

Hot Module Reload (HMR) support for development.

This utility allows reloading individual modules during development without a full application restart, while optionally preserving their reactive state.

Example:

await AirHotReload().hotReload(
  'my_module',
  onBeforeReload: () async {
    // Save any pending state
  },
  onAfterReload: () async {
    // Reinitialize subscriptions
  },
);
