* **New Features**
* Added configurable support for enabling or disabling inline comments.
* Introduced visual indication (strikethrough) for deleted comments in
the comment sidebar.
  * Sidebar now shows when a comment is no longer present in the editor.
* Added a localized placeholder prompt ("What are your thoughts?") in
the comment editor.
* Integrated detailed event tracking for comment actions: create, edit,
delete, and resolve.

* **Improvements**
  * Inline comments are now disabled in shared mode.
* Enhanced synchronization between editor comments and provider state to
remove stale comments.
  * Inline comment features now respect the document’s read-only state.
* Improved mention handling and tracking in comment creation and
editing.
* Comment manager and entities now dynamically track comments present in
the editor.
* Comment configuration updated to enable or disable inline comments
based on settings.

* **Bug Fixes**
  * Prevented comment block creation when in read-only mode.

* **Localization**
