// Because bundlers can now predetermine a static set of binaries we need to ensure those binaries
// actually exists, else we risk a compile time error when bundling the package. This could happen
// if we added a new binary in cpu_profiler.ts, but forgot to prebuild binaries for it. Because CI
// only runs integration and unit tests, this change would be missed and could end up in a release.
// Therefor, once all binaries are precompiled in CI and tests pass, run esbuild with bundle:true
// which will copy all binaries to the outfile folder and throw if any of them are missing.
