## Summary
- Add `NodeContextMenu.vue` using PrimeVue ContextMenu component with
native submenu support
- Rename `SubmenuPopover.vue` to `ColorPickerMenu.vue` (specialized for
color picker)
- Delete old components: `NodeOptions.vue`, `MenuOptionItem.vue`,
`useSubmenuPositioning.ts`
- Wire up context menu converter in `useMoreOptionsMenu.ts`
- Update tests to use hover instead of click for submenus
## Dependencies
**This PR depends on #7113** - the context menu converter infrastructure
PR. It should be merged after that PR.
## Benefits
- Native PrimeVue submenu support with proper keyboard navigation
- Constrained menu dimensions with overflow scrolling (max-h-[80vh])
- Cleaner component architecture with ~280 fewer lines of code
- Better separation: ColorPickerMenu handles only the custom color
picker UI
## Test plan
- [x] Typecheck passes
- [x] Lint passes
- [x] Knip passes
- [ ] Browser tests for submenu interactions pass
- [ ] Manual testing of node context menu
## Screenshots
(Menu UI should look the same, with improved submenu behavior)
