Hyperlane CLI: prompts for private key multiple times instead of once

[k4ctuss]

Summary

When using the hyperlane core deploy command without setting the HYP_KEY environment variable, the CLI prompts for the private key for each chain individually instead of just once. Since there are over 120 chains, this makes the deployment process extremely tedious.

Expected Behavior

The CLI should ask for the private key once and reuse it for all chains during deployment.

Actual Behavior

The CLI repeatedly asks for the private key for every chain in the deployment process.

Steps to Reproduce

1. Run hyperlane core deploy without setting the HYP_KEY environment variable.
2. Observe that the CLI prompts for the private key for every chain individually.

Additional Context

• If HYP_KEY is set, the deployment works as expected, without prompting for multiple private key entries.
• This behavior significantly slows down the deployment process when manually entering the private key.

Would be great to know if this is the intended behavior or if a fix is planned! 🚀
