Module prompt 

Composable prompt construction with variable interpolation.

PromptTemplate supports {variable} placeholders and composable sections (persona, instructions, examples, constraints). Use PromptBuilder for fluent construction.

use daimon::prompt::PromptTemplate;

let tpl = PromptTemplate::new("You are {role}. Today is {date}.")
    .var("role", "a helpful assistant")
    .var("date", "2026-03-03");

assert_eq!(tpl.render_static(), "You are a helpful assistant. Today is 2026-03-03.");
