Rive Editor adds constraint navigation and path simplification

Rive Editor 0.8.5761 adds constraint rows in the Hierarchy and a Target For Inspector panel that lists objects pointing to the current selection.

Edit Vertices now includes Simplify, which removes path vertices within a tolerance while preserving keys and weights.

The update also adds Select Only viewport controls, stage-view rotation, GPU Canvas by default, and fixes for Windows shortcuts, exports, and the web editor.
