ggen-cli-lib 26.5.19

{#- Main entry point for a generated clap-noun-verb CLI
    This is the complete main.rs -- includes mod declarations for
    domain and error modules, all noun modules, and the run() entry.

    Expected variables:
    - interface_name: string (e.g., "ggen")
    - interface_summary: string (e.g., "Ontology-governed compiler interface")
    - commands: array of { name, summary, description, subcommands[] }
      - subcommands[]: { name, summary, about, options[], positional_arguments[],
                         constraints[], examples[] }
        - options[]: { name, long_name, type (flag/value), summary, description,
                       required, global }
        - positional_arguments[]: { name, summary, required }
        - constraints[]: { type, source, target }
        - examples[]: { text }
    - global_options: array of { name, long_name, type, summary, global }

//! Architecture:
//! - CLI Layer (this file): Argument parsing via #[noun]/#[verb] macros
//! - Domain Layer (domain.rs): Pure business logic -- implement your logic there
//! - Error Types (error.rs): Type-safe error handling
