Changes Made

Added a prominent version notice warning at the top of the README (after the badges, before "Using Evolve" section) that states:

⚠️ Version Notice: Do not use tags or releases before v1.0.0. Pre-v1 releases are not considered stable and may contain breaking changes.

This warning will help users understand that they should avoid using pre-v1 releases.
