/**
 * Structural SQL Parser for Composition IR
 *
 * SQL-context-aware parser that produces a {@link QueryIR} for the composition
 * engine. Unlike MJLexer (which splits purely on brace patterns without regard
 * for SQL context), this parser understands:
 *
 * - `'{{ X }}'` is a template expression inside a SQL string literal
 * - `/* ... {{ X }} ... *​/` is a template token inside a block comment
 * - `WITH ... AS (...)` boundaries for CTE detection
 * - Top-level ORDER BY position (not inside subqueries/window functions)
 *
 * The parser produces Fragment[] sequences that the composition engine
 * manipulates structurally (hoisting CTEs, stripping ORDER BY, renaming
 * references) before the IR renderer emits SQL with template tokens intact
 * for Nunjucks evaluation.
