📝 Walkthrough

Summary by CodeRabbit

• Bug Fixes
  • Fixed an issue where undo/history was incorrectly recorded during editor initialization, causing unexpected undo behavior. History recording now properly defers until the editor is fully initialized.

Walkthrough

This PR modifies the undo history registration to defer recording history updates until the editor completes initialization. A new internal isReadyForHistory flag starts as false and blocks the history update listener from processing changes. The flag is set to true inside the CLEAR_EDITOR_COMMAND and CLEAR_HISTORY_COMMAND handlers, after closing any active undo group, allowing subsequent editor updates to be processed by the existing merge and state logic.
