* Done! The changes have been implemented and all type checks pass:
1. ✅ Added `ClickToComponentEnableMessage` interface
2. ✅ Updated `ClickToComponentMessage` type to include `'enable-button'`
3. ✅ Modified the `'ready'` handler to send enable message back to iframe using `event.source`
The parent will now automatically send the enable-button message when it receives ready from the iframe.
* Cleanup script changes for task attempt f2d1a5b0-9c5b-4847-9fb8-f5851fca59d3
