//! # origin-chain-node CLI canonical
//!
//! Phase 1.6+ Slice 1 (v0.0.10): **CLI skeleton + genesis preset listing canonical**.
//!
//! ## Sub-comandos canonical disponibles
//!
//! ```text
//! origin-chain-node                       # default: version canonical
//! origin-chain-node version               # print runtime version canonical
//! origin-chain-node list-presets          # enumera 3 genesis presets canonical
//! origin-chain-node print-preset <id>     # JSON-serialized RuntimeGenesisConfig
//! origin-chain-node info                  # full runtime metadata canonical
//! ```
//!
//! ## Roadmap canonical Phase 1.6+ (multi-slice canonical)
//!
//! - **Slice 1** (v0.0.10 ESTA): CLI skeleton + preset listing canonical
//! - **Slice 2** (v0.0.11): `origin-chain-types` fully no_std refactor canonical →
//!   `WASM_BINARY` canonical via `substrate-wasm-builder`
//! - **Slice 3** (v0.0.12): real `sc_service::ChainSpec` builder canonical
//!   consuming GenesisBuilder API canonical
//! - **Slice 4** (v0.0.13+): full `sc-service` builder canonical
//!   (consensus + JSON-RPC + networking + telemetry)
//!
//! ## Filosofía canonical
//!
//! Esta CLI canonical es la **primera ventana del barquero al mundo**: cualquier
//! humano o AGI puede ejecutarla canonical y ver qué configuraciones canonical
//! ofrece Origin Chain — sin necesidad de leer source code canonical. El
//! `list-presets` canonical es transparency canonical: las 3 distribuciones
//! posibles canonical están a la vista canonical, BM V2 incluida canonical.
