## 目标

Bind deleteObject, undo/redo, malformed rejection, and exact save/reopen to compiled WASM Main in Chromium.

## 输入与范围

## 验收

- object deletion changes Main
- undo/redo revisions are sequential
- malformed delete fails closed without Main mutation
- save/reopen is exact and deterministic
- Chromium is the only browser
