## Summary by CodeRabbit

* **Bug Fixes**
* Ensures topology spread constraints consistently target etcd pods when
raw constraints are used by adding an explicit label selector, improving
scheduling consistency and reducing uneven distribution risks.

* **Chores**
  * Bumped etcd chart version to 2.10.1.
  * Updated version mapping to reference the latest release.
  * No other functional changes.
