 * - Tree-sitter may fail with "Invalid argument" error on very large files (1000+ lines)
 * - When this occurs, Lien automatically falls back to line-based chunking
 * - Configure fallback behavior via `chunking.astFallback` ('line-based' or 'error')

 * @param options - Chunking options
 * @returns Array of AST-aware chunks
