[FranckDSA]

• Add silo_xETH_scETH_market address to ChainValues.sol
• Update CreateStakedSonicETHMerkleRoot.s.sol to include ERC4626 integration
• Generate updated StakedSonicETHStrategistLeafs.json with new market leafs

Greptile Summary

This PR integrates the Silo xETH-scETH market on the Sonic blockchain into the StakedSonicETH vault system. The changes enable the vault to interact with Silo's ERC4626-compliant lending market for xETH collateral and scETH borrowing, expanding yield generation opportunities.

The integration follows the established pattern in the boring-vault codebase for adding DeFi protocol support. First, the new market address is registered in ChainValues.sol, which serves as the centralized address registry for all supported protocols across different chains. Next, the Merkle root generation script is updated to include ERC4626 vault operations for the new Silo market. Finally, the strategist leaf configuration is regenerated to include all necessary function calls for depositing, withdrawing, and managing positions in the Silo market.

The vault system uses Merkle trees to define and verify allowed operations, ensuring that only pre-approved functions can be executed by strategists. This approach provides security while enabling flexible DeFi integrations. The new Silo integration allows the vault to earn yield by depositing ETH as collateral and potentially borrowing scETH, following Silo's isolated lending market model.

Changed Files

Filename	Score	Overview
test/resources/ChainValues.sol	5/5	Added silo_xETH_scETH_market address to SonicMainnet configuration
script/MerkleRootCreation/Sonic/CreateStakedSonicETHMerkleRoot.s.sol	3/5	Added ERC4626 integration for Silo market with potential array initialization issue
leafs/Sonic/StakedSonicETHStrategistLeafs.json	4/5	Generated Merkle tree configuration with 217 operations including new Silo market support

Confidence score: 3/5

• This PR has moderate risk due to a potential bug in the script and extensive generated configuration changes
• Score reflects the straightforward address addition but concerns about duplicated array assignment and large generated file changes
• Pay close attention to the CreateStakedSonicETHMerkleRoot.s.sol script for the array initialization issue
