//! MiniJinja rendering and prompt-local command expansion.
//!
//! Two distinct surfaces share the renderer:
//!
//! - Hooks render Jinja only — no `!`exec(...)`` substitution.
//! - Prompts render Jinja first, then expand `!`exec(...)`` and ``exec(...)``
//!   markers as a second pass. The shell commands run with a 30s timeout.
