## Summary by CodeRabbit

* **Refactor**
* Component reference handling moved to the public OCI bindings,
consolidating parsing/resolution into a shared implementation.
* Legacy internal reference parser and its option surface were removed;
CLI commands use the unified binding with no functional change.
* Tests updated to the new bindings; some legacy internal tests were
removed.
