v0.3.0-beta.0 - Adapter foundation

Summary

CEWP v0.3.0-beta.0 introduces the first adapter foundation layer for Coordinator Mode.

This release does not add external provider support yet. The current production provider remains codex-exec, but the internal adapter boundary is now cleaner and better prepared for future provider experiments.
