Bone Flow Editor v1.0.42 / Realtime Preview #001 Build 1.0.10
Issue: FIT zoom changed but Preview container kept its fixed vertical height in VS Code Webview.
Fix: FIT now writes the computed height directly to host, preview panel, preview surface, iframe, and editor source panel when present.
Scope: Preview-only and Editor + Preview.
No Shape/Joint renderer rewrite.
