perf(editor): cache M2/WMO models across rebuilds, only clear instances

Browse source 
The editor's rebuildObjects path was destroying every cached model and
re-uploading it on every (debounced) change. Added M2Renderer::clearInstances
that drops only the instance list while keeping models loaded. Editor's
clearObjects switches to clearInstances (M2) + clearInstances (WMO),
and persistent path->modelId maps survive across rebuilds. clearTerrain
fully evicts when loading a new zone.
