Steps to reproduce

1. Run midnight-shell.sh to launch and enter container
   ./midnight-shell.sh

2. Invoke "./midnight-node wizards generate-keys" and use the default prompts
   ./midnight-node wizards generate-keys

Result

root@90d97d7ee4da:/# ./midnight-node wizards generate-keys
This 🧙 wizard will generate the following keys and save them to your node's keystore:
→  an ECDSA Cross-chain key
→  an ED25519 Grandpa key
→  an SR25519 Aura key
It will also generate a network key for your node if needed.

> node base path ./data

Start with midnight-shell.sh and reproduce the documented commands inside the container, comparing key generate with key insert. Investigate the midnight-node key insert entry point and the Ubuntu 24.04/Docker environment; done means key insertion no longer exits with status 132 or the supported CPU/runtime requirements are clearly documented.
