The AI agent summary is:

Done. Summary of documentation changes:

• Layer Effects (interface/scene-editor/layer-effects/index.md): Added an "Adding an effect from the store" section covering the new ability to browse ready-made effects with bundled assets (e.g. Skybox), noting the store lists only effects valid for the selected layer.
• GDevelop AI (interface/ai/index.md): Added an "Attaching images and files to your message" section describing the new attach button / drag-and-drop, and that attached images can be converted into project resources.

The 3D physics character jump fix and in-game/3D-editor changes were internal behavior fixes or editor internals not described in the docs, so they needed no updates.

Please review the changes carefully before merging.
