BREAKING CHANGES: Several APIs/options have been renamed:
- `type: "inline" | "overlay" | "modal"` has been changed to `position: "inline" | "overlay" | "modal"`
- `createContentScriptUi({ ... })` → `createShadowRootUi({ ... })`
- `createContentScriptIframe({ ... })` → `createIframeUi({ ... })`
- `onRemove` is now called ***before*** the UI is removed from the DOM, previously it was called after the UI was removed
