Greptile Summary

This PR adds a local two-chain Besu QBFT demonstration with generated genesis configurations, account derivation, Docker Compose orchestration, and operational documentation.

• Adds templates and scripts for initializing, starting, inspecting, and cleaning two independent Besu chains.
• Documents chain accounts, ports, configuration, prerequisites, and the local-devnet security model.
• Updates ignore and license configuration for generated artifacts and JSON templates.

Confidence Score: 3/5

The PR is not yet safe to merge because the previously reported validator-key exposure remains unresolved.

The generated validator key is still written mode 0644 beneath mode-0755 directories, so an unrelated local user can read a custom mnemonic’s sole-validator key and impersonate that validator.
