Latest PRs merged into our repository.

Add more Events and functions on Agg Contract (#1930)

https://github.com/yetanotherco/aligned_layer/pull/1930

• Adds functions to set the Risc0 verifier address and additional events on the agg contract.

Update EigenLayer Contracts for Devnet (#1932)

https://github.com/yetanotherco/aligned_layer/pull/1932

Local networks were running on old versions of Eigenlayer. This PR updates them, and decouples our middleware contracts from the eigenlayer contracts.

Changes:

• Updates EigenLayer contracts to v1.4.2 for local devnet.
• Adds EigenLayer contracts as a submodule; middleware retains the previous version due to breaking changes and compatibility issues.
• Updates Foundry to version 1.1.0-stable.
• Adds a new target to deploy all contracts: make anvil_deploy_all_contracts.
• Bumps EigenSDK to v0.2.0-beta.1 for Devnet.
• Updates DEVNET addresses in the Aligned SDK.
• Enables optimizer in contracts/foundry.toml.
• Migrates operator registration for Devnet.
• Updates documentation and CI.

Re-add Ethereum Package for local networks (#1937)

Aggregation mode is now using Ethereum as a DA layer, which requires a beacon node running. For this reason, we added a way to launch our local network with Ethereum Package as an alternative to Anvil.
