Check settings file exists before checking its contents

* Visualize draft point when near axes (only works on XY rn due to quaternion rotation issue)

* Slightly better quaternion rotation

* Actually snap new profiles to the X and Y axis

* Add snapping behavior while dragging

* Fix flickering on non-XY planes

* Add some fixture additions to support click-and-drag tests

* Add new test to verify snapping behavior

* Make the editor test fixture auto-open and close as needed

* All feedback except absolute lines

* Use `lineTo` for lines that have snapped

* Get other existing tests passing after switching to `lineTo` when snapping

* A snapshot a day keeps the bugs away! 📷🐛 (OS: ubuntu-latest)

* Re-run CI
