Pull Request Overview

This PR refactors the existing distributed dev-utils examples into a unified, simplified administrative CLI (admin-cli). Key changes include:

• Removal of all dev-utils example files and their Cargo.toml configuration.
• Introduction of admin-cli with a modular command-based structure covering token, domain, pool, provider, work, node, wallet, and test commands.
• Updates to the project’s top-level Cargo.toml and Makefile to reflect the transition to admin-cli.
