Add simplified Unity sample for better developer onboarding

[tomicz]

🎯 Purpose

This PR adds a simplified Unity sample project (Tomicz.SimpleExample.Unity) to complement the existing comprehensive sample.

🤔 Problem

While the existing Reown.AppKit.Unity sample is excellent for production applications, it can be overwhelming for developers who just want to:

• Quickly understand core AppKit concepts
• Get started with basic wallet integration
• Learn the essential API patterns

💡 Solution

This new sample provides:

• Single-file implementation - Everything in WalletController.cs
• Essential features only - Connect, disconnect, get address/balance
• Clear, copy-pasteable code - Easy to understand and adapt
• Minimal dependencies - Just the core AppKit functionality

🎯 Target Audience

• Developers new to Web3/Unity integration
• Those who prefer learning through simple examples
• Teams who want to quickly prototype wallet features

🤝 Relationship to Existing Sample

• Existing sample: Production-ready, full-featured application
• New sample: Learning-focused, minimal implementation
• Both serve different purposes and complement each other

📚 Benefits

• Faster developer onboarding
• Clearer API documentation through code
• Easier to understand core concepts
• Better developer experience for quick integration

🔍 What's Included

• Simple UI with essential buttons
• Core AppKit initialization
• Wallet connection/disconnection
• Account and balance display
• Clean, commented code

This sample doesn't replace the existing one but provides an alternative entry point for developers who prefer simpler examples.

Hello,

Thank you very much for opening the PR 🙏

I understand how newcomers may feel overwhelmed when learning a new tool, and our main sample may contribute to that. While I try to keep it as simple as possible, it still uses multiple scenes and includes some extra scripts, which contributes to complexity.

That said, we have many simpler sample projects in the /playground directory. The main differences between them and the sample are that the sample uses more AppKit features, is actively maintained, is utilized by CI, includes error monitoring tools, and its artifacts are distributed on TestFlight and Firebase.

Instead of introducing another sample project, we could link to one of our basic playground projects from the docs.

Our documentation already provides very detailed installation instructions and provides basic code snippets, as well as more in-depth examples in the Usage section. Do you think our doc aren't clear for newcomers?

I have also added a detailed readme file to the sample project.

Yes, I agree this would be a perfect addition to Playgrounds/ Do you want me to move it there, or will you do it?
