feat(editor): release callout (#13896)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

* **Refactor**
* Callout is no longer gated as an experimental option — it now
consistently appears in the editor’s slash menu and toolbar where
applicable.

* **Tests**
* End-to-end slash-menu tests updated to expect the Callout item in
search results and adjusted item ordering.

* **Chores**
  * Repository ignore rules updated to exclude .kiro files.
