//! CODA Prompt Manager
//!
//! A template-based prompt management system using minijinja. Supports
//! loading `.j2` template files from directories and rendering them with
//! structured context data.
//!
//! # Usage
//!
//! ```
//! use coda_pm::{PromptManager, PromptTemplate};
//!
//! let mut pm = PromptManager::new();
//! pm.add_template(PromptTemplate::new("greeting", "Hello, {{ name }}!")).unwrap();
//! let rendered = pm.render("greeting", minijinja::context!(name => "World")).unwrap();
//! assert_eq!(rendered, "Hello, World!");
//! ```
