Add a new Anchor program example demonstrating cross-program invocations (CPI)

[0xTan1319]

Summary

We’d love to add a new Anchor-based Solana program example that demonstrates cross-program invocations (CPI). This is a key concept for many advanced Solana smart contracts, and a good educational resource for developers learning Anchor.

What should this example do?

• Use Anchor framework
• Include a simple CPI to another Anchor program (e.g. a counter or a token program)
• Include detailed comments explaining each step
• Provide a matching TypeScript client test demonstrating the CPI in action

Why is this valuable?

• CPI is fundamental for advanced Solana contracts
• This would help newcomers understand Anchor patterns
• Expands the coverage of program-examples

How to get started

• Clone the repo
• Add a new folder under anchor/cpi-example
• Follow the structure of other Anchor examples
• Test your code with anchor test
• Open a pull request with your contribution

Hey, new to SOL dev but I think I can do this.

How long should it take about, I think maybe in the next few days I can finish it for sure but I wanna work through some of these examples first so I can get used to your guys style.

Best!
