Description

## Feature request

### What are you trying to achieve?

Reduce the package size by switching to ESM-only.

### When you searched for similar feature requests, what did you find that might be related?

Followup to #2981.

### What would you expect the API to look like?

I think support for CJS projects is probably a must for a project like Sharp, so it can't just be migrated to ESM-only because of dynamic imports. So it would need a change in the API (breaking change), like `sharp = await loadSharp()`.

### What alternatives have you considered?

Keep ESM+CJS. Problem: increase in size, files are duplicated.

### Please provide sample image(s) that help explain this feature

Research direction

Review the related discussion in issue #2981 and the ESM/CJS and dynamic-import constraints described here. Clarify the proposed breaking API and migration scope, including how CJS projects would be supported. Done would require an agreed design before implementation begins.
