## Summary by CodeRabbit

* **Documentation**
* Updated all quickstart guides and tutorials to reference publishable
keys instead of anon keys for Supabase client initialization.
* Simplified environment variable setup instructions across multiple
framework guides by removing anon key configuration requirements.
* Clarified usage of publishable keys in step-by-step setup
documentation for various frameworks and platforms.
