/**
 * resolver-strip — build-mode pass that eliminates `zodResolver` from the
 * `@zod-to-form/react` `useZodForm` hook when the user has validation
 * optimization enabled (FR-013).
 *
 * The runtime hook keeps a static `import { zodResolver } from
 * '@hookform/resolvers/zod'` so non-optimized users get the resolver via
 * normal ESM evaluation. When optimization is on, every call site sits
 * inside an `isOptimized ? undefined : zodResolver(...)` ternary, and
 * the call is dead code — but Rollup's tree-shaker can't prove that
 * statically because the ternary's condition is a runtime value.
 *
 * This pure helper rewrites every `zodResolver(rhfCast(schema))` call
 * in `useZodForm` source to a literal `undefined`. After the rewrite
 * the import has zero remaining references, and Rollup eliminates the
 * import statement automatically — closing the gzipped delta the
 * benchmark page asserts.
 *
 * Pure: takes source + a "should-strip" flag, returns transformed source
 * + sourcemap. No I/O, no plugin context. The plugin's `transform` hook
 * decides WHEN to call it based on file id + config.
