Core:
- Add addMode, removeMode, renameMode, setDefaultMode to SceneGraph
- Add editor actions with full undo: addMode, removeMode, renameMode,
setDefaultMode, duplicateMode, setActiveMode
Vue SDK:
- Wire all mode and collection actions through SDK helpers
- Add mode rename state to dialog composable
- Remove HTMLInputElement casts from commit handlers
UI:
- Mode management lives in the table column headers (Figma-style):
double-click to rename, right-click for context menu (rename,
duplicate, set as default, delete), + button after last mode column
- Collection ⋯ dropdown menu with rename and delete
- Use shared menu UI styles throughout
- i18n for en, ru, zh-CN
