/**
 * postgres-mcp — Code Mode Auto-Return Transform
 *
 * Transforms user code so the last expression statement is implicitly
 * returned from the async IIFE wrapper.  Mimics Node REPL / Chrome
 * DevTools semantics where bare expressions surface their value.
 *
 * The transform is intentionally heuristic (string-based, not AST)
 * because the code runs in a sandboxed vm.Script that already
 * handles syntax errors.  Edge-case misfires are safe — they either
 * produce a benign return of the last expression or leave the code
 * unchanged (returning undefined, the previous behavior).

/**
 * Transform user code so the last expression statement gets an

 * Examples:
 *   `pg.help()`                       → `return pg.help()`
 *   `const r = await foo(); r`        → `const r = await foo(); return r`
 *   `return 42`                       → `return 42`          (no change)
 *   `for (const x of xs) { ... }`    → unchanged             (control flow)
