/**
 * Re-applies the `NG_BUILD_*` variables the caller just disabled onto an
 * `@angular/build` that was already loaded — see the README FAQ and #107 / #114.
 * Nx requires `@angular/build/private` before resolving the builder, and
 * `environment-options.js` snapshots the variables on first load, so the caller's
 * writes land too late. Mutating the cached exports works because both consumers
 * re-read the property per call; evicting the module does not, as they keep a
 * reference to the stale namespace.
 *
 * Must run before this package imports `@angular/build`, or it detects our own
 * load. No match means "not loaded yet" *or* "cannot see it" (ESM), not "healthy".
