query_builder.rs

//! Tree-sitter query builders for symbol extraction
//!
//! This module contains functions that create compiled tree-sitter queries
//! for extracting symbols from source code. Each language has two query types:
//!
//! - **Basic queries** (`*_query`): Extract only symbol definitions
//! - **Super-queries** (`*_super_query`): Extract symbols AND imports in one pass
//!
//! Super-queries are more efficient for full file analysis as they require
//! only a single AST traversal.
