scene.revert

Discard a scene's unsaved edits and restore its saved scene.json.

Takes an optional scene name; without one the active scene reverts.

The undo for scene.clean / scene.remove and any edit-mode change, and the counterpart to scene.save. Every edit since the last save lives in the scene's dirty overlay until you commit it; this throws that overlay away and respawns the scene from its saved state.

Because the dirty overlay belongs to the scene ASSET (not the runtime layer), a revert works whether or not the scene is currently loaded — pass a name to revert a specific scene, or omit it for the active one. This reverts only the edit-mode dirty overlay; it is not the play-mode baseline restore.

Returns { scene, discarded } — discarded is true when unsaved edits were thrown away, false when the scene was already clean.
