feat: add contract verification and interaction scripts to Makefile

[2PykeETH]

PR Description

Summary

This PR enhances the Makefile with commands for contract verification and streamlined interaction workflows on different networks.

What's Changed

• ➕ Section Header: Verification & Interaction

  • Added clear section divider for readability and logical grouping.

• ➕ verify-mainnet

  • Command to verify deployed contracts on Etherscan using forge verify-contract.
  • Supports chain-id 1 and uses the configured ETHERSCAN_API_KEY.

• ➕ interact-local

  • Command to run the InteractionScript on a local network (http://localhost:8545).
  • Useful for debugging and quick iteration.

• ➕ interact-testnet

  • Command to run the InteractionScript on a testnet (configured via SEPOLIA_RPC_URL).
  • Provides a bridge for testing interactions against a live environment before mainnet.

• 🧹 Minor formatting adjustment (--broadcast spacing) for consistency.

Why

• Streamlines verification process post-deployment to ensure contracts are transparent and visible on explorers.
• Simplifies interaction testing across local, testnet, and mainnet without needing manual forge commands.
• Improves Makefile readability with dedicated section headers.

Impact

• ✅ Developers can verify contracts with a single command.
• ✅ Interaction scripts can now be run easily in both local and testnet environments.
• ✅ Improved project automation and developer experience.

Next Steps

• Add interact-mainnet for production interaction workflows.
• Extend verification commands for Polygon, Arbitrum, and Optimism explorers.
