Use ignore_dce_annotations for runtime transpiled files.

Bun processes dce annotations, which makes sense for a bundler, but less at a runtime. If a DCE annotation lies, it causes behavioral differences.

function isBun() {
  try {
    /* @__PURE__ */ null(null);
    return true;
  } catch {
    return false;
  }
}

console.log(isBun());
