feat: Custom App Metadata

[stevensJourney]

Overview

This allows clients to specify application metadata when calling powerSync.connect. This Record of String values is logged in the PowerSync service logs, which can be used for debugging and analytics. For context: powersync-ja/powersync-service#413

The Example Node and Supabase React Todolist demos have been updated to post their application versions to the service.

powerSync.connect(connector, {
  appMetadata: {
    app_version: APP_VERSION
  }
});

Tested this on Staging by running the example-node demo, connecting to a staging instance.
