Feature Request: Implement CLI for RGB Lightning Node

[bitwalt]

Hi!
I noticed there’s an empty cli.rs file in the repository, which looks like a great place to implement a command-line interface (CLI) for RLN.
A CLI would make it much easier to interact with the RGB Lightning Node directly from the terminal — allowing developers and users to call core functions without needing to write custom scripts or integrate with APIs manually.

---

Goals

• Provide a simple and consistent command-line interface for managing RGB Lightning Nodes.

• Enable easy execution of common node operations, such as:

  • Node initialization
  • Asset issuance and transfer
  • Channel management
  • Querying node status and balances

---

Proposed Features

• Command grouping by functionality (e.g. node, asset, channel)
• Output formats: JSON (for scripting) and human-readable text (for CLI users)
• Configurable verbosity/logging levels
• Robust error handling and helpful usage guidance

---

Motivation

This feature will improve developer experience and usability by making RLN’s capabilities easily accessible from the terminal. It also paves the way for future automation and scripting tools built around the CLI.

The idea is good, but for now we think the swagger interface, that also allows to copy curl commands, is enough. Maybe in the future we'll add a CLI, but that will use the openapi spec to lower down the maintenance burden.
