- ✅ **2b — `ipc/handlers.ts`:** Replace `workflow:advance` implement-phase block with branching-toggle logic
- ✅ **3 — `GitSettings.tsx`:** Create new settings component with pill toggle
- ✅ **4 — `SettingsPage.tsx`:** Add `"git"` section type, import, nav item, content render; fix both unicode glyphs
- ✅ **5 — `globals.css`:** Append toggle-row + pill toggle + maximize-btn CSS
- ✅ **6 — `index.ts`:** Add `ipcMain` to import; add `window:toggleMaximize` handler + maximize/unmaximize events inside `createWindow()`
