v1.9.1

⭐ Features

This release enables users to create a local signature aggregator instance. Local signature aggregator instances can be spun automatically when running avalanche blockchain deploy or avalanche blockchain convert commands or started manually with avalanche interchain signatureAggregator start. Once a local signature aggregator instance is created, its signature aggregator URL can be used externally outside of CLI.

This release also adds support for deploying the validator manager on a different blockchain (e.g., C-Chain). Running the validator manager outside the L1 ensures it continues operating even when most L1 validators are inactive. With this setup, you can add new validators and safely recover L1 operations.
