Description

Before that, I want to run an alternative by you: would it make more sense to add this to defineContentScript (as an option like cssInjectionMode, matches, etc) instead of wxt.config.ts?

export default defineContentScript({
  iffeName: "example",
  // OR `globalName: string | boolean`, letting people disable the iffe name in the  output as well as give it a different name.

  main() {
    // ...
  }
})

In this version, it would default to true and the name would be generated based on the content script name, but in the next major version would could change the default to false so a name isn't even generated in the first place.

Research direction
Review the current implementation of `defineContentScript` in the WXT framework (likely in packages/wxt/src/...). Understand how content script options are processed and how the IIFE name is generated during the build. Look at the linked PR #1897 discussion for context. Determine the best approach to add an `iffeName` or `globalName` option to the configuration.
