Good First Issue

説明

When using the Pen tool to draw a path and pressing Ctrl+Z multiple times, the preview line (showing the segment from the last anchor to the cursor) would disappear after a certain number of undos.

調査方針: Investigate the undo/redo system in Graphite's source code to understand how it affects the Pen tool's preview line. Look at the history management module (likely in a file such as `history.rs`) and the Pen tool's state handling during undo operations. Check the issue for any linked PRs or comments for additional context, though none exist currently. Reproduce the bug locally to identify the specific undo step causing the preview to disappear.
