SC: Set Up Soroban Environment for YieldForge

Description: Configure the Soroban development environment to build and test smart contracts for the YieldForge stablecoin yield farm, ensuring compatibility with Stellar’s testnet.

Tasks:

Install Soroban CLI and Rust toolchain.
Set up a testnet environment for contract deployment.
Create a sample contract to verify setup (e.g., store user balance).

Acceptance Criteria:

Soroban CLI deploys a sample contract to Stellar testnet.
Sample contract is invoked successfully (e.g., stores/retrieves data).
Setup is documented in the repository.

Start by reviewing the repository contents and the Soroban CLI and Rust toolchain requirements. Set up Stellar testnet deployment, create the sample contract that stores and retrieves a user balance, and document the setup in the repository. Done means the contract deploys and can be invoked successfully on testnet.
