Function cli_output 

pub fn cli_output(value: &Value, format: OutputFormat) -> String

Dispatch output formatting by OutputFormat.

Equivalent to calling output_json, output_yaml, or output_plain directly.

use agent_first_data::{cli_output, OutputFormat};
let v = serde_json::json!({"code": "ok"});
let s = cli_output(&v, OutputFormat::Plain);
assert!(s.contains("code=ok"));
