Editor picking selection order is incorrect

User Problem

Editor picking selection order is incorrect. Objects behind others sometimes get priority.

Expected Behaviour

Picking should behave the same way as the scene is rendered: whichever object appears "on top" should be prioritized.
This may require updating the picking strategy to be render-target-based.

One approach I previously implemented in Overload was to render the scene to a render buffer, assigning each actor/node a unique color (derived from its actor_id/node_id). Then, when a click occurs in the scene view, the color under the cursor is read to identify the selected object.
