6/// Parser that returns raw text unchanged.
7///
8/// This is the simplest output parser, useful when no structured parsing
9/// is needed and the model's raw text output is sufficient.
10///
11/// # Examples
12///
13/// ```
14/// use synwire_core::output_parsers::{OutputParser, StrOutputParser};
15///
16/// let parser = StrOutputParser;
17/// let result = parser.parse("Hello, world!").unwrap();
18/// assert_eq!(result, "Hello, world!");
19/// ```
