Function parse_json_response 

pub fn parse_json_response(text: &str) -> Option<Value>

Strip markdown code fences (```json … ```) and parse the inner JSON.

If the text is plain JSON (no fences), it is parsed directly. Returns None when the text is not valid JSON after stripping.

Example

let text = r#"```json\n{"title": "Plan"}\n```"#;
let value = parse_json_response(text).unwrap();
assert_eq!(value["title"], "Plan");
