The AI agent summary is:

Documentation changes made:

• Scene Editor (interface/scene-editor/index.md): documented the new visibility toggle in the Instance Properties panel that lets an instance be hidden when the scene starts.
• External Tilemap (objects/tilemap/index.md): documented the new built-in collision (Enable collision + Class filter properties) so a tile map can generate its own hitboxes without a separate collision mask object, and noted that external tile maps can now be read/modified at runtime through events.

All edits stay within docs/gdevelop5/ and avoid the auto-generated reference/extension files.

Please review the changes carefully before merging.
