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, json_result, OutputFormat};
let v = json_result(serde_json::json!({"ok": true})).build().expect("valid afdata event");
let s = cli_output(v.as_value(), OutputFormat::Plain);
assert!(s.contains("kind=result"));
