EditorLayer::tick_autosave writes .nmsscn.autosave.json beside the
scene every 2 minutes while dirty (Editor mode, saved scenes only): world
snapshot via the new serialization::entity_files_for_save on the main
thread, JSON encode + atomic temp-and-rename write on a background thread —
no file I/O inside the frame. Manual save deletes the autosave; loading a
scene with a newer autosave offers Restore/Discard, and a restored scene
keeps the real .nmsscn path and starts dirty.

Roadmap item 35 (Tier 1), autosave half of debt #17.
