//! Centralized prompt definitions for all AI-powered commands.
//!
//! Prompts and schemas are stored as template files under `prompts/` and
//! embedded at compile time via `include_str!`. Dynamic prompts use
//! Minijinja for rendering.
//!
//! Directory layout:
//! ```text
//! crates/sr-ai/src/prompts/
//! ├── commit/
//! │   ├── system.txt
//! │   ├── user.txt.j2
//! │   ├── patch.txt.j2
