Plugin context excludes majority of global object variables/methods

[Yanrishatum]

Describe the bug
Current plugin launcher omits most variables/methods from global object, for example queueMicrotask, setTimeout, setImmediate, setInterval, btoa, atob, structuredClone.

To reproduce
The following plugin would not work, due to setTimeout being undefined:

module.exports = function initPlugin() {
  setTimeout(() => console.log(""), 1000);
}

Additional context
This is likely an oversight when creating the context for Script.runInContext call to execute the plugin as it overrides global object.
