Description

Drag from a ruler to create a horizontal or vertical guide line. (Drag it back into the ruler to delete it.) This is positioned in document space. View > Guides should go next to the existing View > Rulers menu to toggle their visibility. Snapping works with them like they're a line (just without endpoints, since guide lines are infinitely long). Like everything else that you can drag in Graphite, Esc and right-click cancel a drag, putting it back where it began (or deleting it if this was just brought into existence by dragging out of a ruler).

Research direction
Examine the existing ruler implementation in Graphite to understand how drag events are handled when dragging from a ruler. Look at the View menu to see how the Rulers toggle is implemented, as the Guides toggle should be placed similarly. Investigate the snapping system (likely in the viewport or canvas module) to integrate guide lines as snapping targets. The main implementation will involve creating new data structures for guide lines, handling drag, snapping, and rendering. Review related pull requests or comments for additional context.
