/**
 * Executes the Expand command to transform a compact plan into an expanded plan.
 *
 * Reads the compact plan from disk, parses and validates it, loads templates (including user templates),
 * validates template references, expands the plan, and emits the expanded plan as YAML or JSON.
 *
 * @param args - Command arguments:
 *   - inputFile: Path to the compact plan file (YAML).
 *   - outputFile: Optional path to write the expanded plan; if omitted the result is printed to stdout.
 *   - format: Output format, either `"yaml"` or `"json"`.
 *   - verbose: When true, emits additional progress information.
 *
 * Exits the process with code 1 on file read, YAML parse, or validation failures.
