feat: Enhance TokenCreation Contract with Inheritance & Storage Variables

[cantinaverse]

Summary

This PR expands the TokenCreation contract by introducing inheritance from OpenZeppelin’s ERC20 and Ownable contracts, along with storage variables for token metadata and creator tracking. These changes set the foundation for a fully functional and customizable token deployment system.

---

Key Changes

• Contract Inheritance

  • TokenCreation now inherits from ERC20 and Ownable, providing standard ERC20 functionality and secure ownership controls.

• Added Storage Variables

  • uint8 private _decimals → defines token decimal precision.
  • uint256 public maxSupply → enforces token supply cap.
  • string private _description → stores descriptive metadata for the token.
  • string private _imageUrl → allows optional image/logo association for UI integrations.
  • address public creator → tracks the original deployer/creator of the token.

• NatSpec Section Update

  • Added section documentation for Storage Variables to improve readability and clarity.

---

Why This Change?

• Establishes the core metadata structure for custom token creation.
• Ensures supply control and token identity management.
• Enables factory-driven deployment while preserving creator attribution.
• Improves developer experience with clear NatSpec comments.

---

Next Steps

• Add constructor logic for initializing token name, symbol, decimals, and metadata.
• Implement minting logic with supply cap enforcement.
• Introduce factory contract integration for dynamic token deployment.

---

Notes

This update transitions TokenCreation from a placeholder contract into a functional ERC20 framework, ready for further feature development like metadata handling, supply constraints, and minting/burning capabilities.
