Product update

This week's release focuses on the editor: reusable tools, a full undo system, and snapping that reads the drawing.

Added

• Custom tools & stamps — Save any styled markup or measurement as a reusable tool from the Properties panel, and upload your own SVG stamps. Tools can be personal or shared with the workspace, and are managed under Settings → Tools.
• Undo/redo + History panel — Every markup and measurement edit is undoable with ⌘Z / ⇧⌘Z. The History panel lists each step by name and lets you jump back to any earlier state. History is saved with the document and survives a reload.
• Snap to drawing elements — Snapping now reads the PDF's vector geometry, so points land on wall corners and line endpoints. Alignment guides and the page grid are separate toggles, and all three modes work while drawing, moving, and resizing — for measurements as well as markups.

Changed

• Freeform polygons & clouds — Per-vertex editing, interior selection, bounding-box resize, and cloud-arc size presets. New line types: dash-dot, long-dash, and dash-dot-dot.
• Measurement selection — Measurements now use the same selection handles as shapes: move, vertex edit, resize, and rotate, all through the same undo pipeline.
