//! Grammar definitions for source languages
//!
//! This module provides grammar definitions for each supported source language.
//! Grammars can be defined using tree-sitter or pest PEGs.
//!
//! # Supported Languages
//!
//! - Python (for depyler → Rust)
//! - Bash (for bashrs → Rust)
//! - C (for decy → Rust)
//! - TypeScript (for decy → TypeScript target)
//! - Ruchy (standalone language)
