## Summary
- Upgrade `ink` from 5.1.1 to 6.8.0 in twenty-sdk (React 19 required, no
API breaking changes)
- Upgrade `react`/`react-dom` from 18 to 19 and
`@types/react`/`@types/react-dom` to 19 in twenty-sdk
- Enable `incrementalRendering` — only redraws changed lines instead of
full output, reducing flickering
- Pause the animation timer when the pipeline is not actively building
or syncing, so Ink stops re-rendering and the terminal becomes
scrollable (fixes inability to scroll up to read errors)
- Remove `AnimationProvider` context — derive animation frames from
`Date.now()` directly in `useStatusIcon`
- Export `NavigationMenuItemType` from `twenty-sdk` (re-exported from
`twenty-shared/types`)
- Add dedicated NavigationMenuItem integration tests to postcard-app
(unique positions, unique identifiers, valid object references)
## Test plan
- [ ] Run `twenty dev` and verify the TUI renders normally during
build/sync
- [ ] Trigger an error and verify the terminal output freezes and
becomes scrollable
- [ ] Verify that after fixing the error, the TUI resumes animating on
next build cycle
- [ ] Verify `import { NavigationMenuItemType } from "twenty-sdk"` works
- [ ] Run postcard-app integration tests and verify new
NavigationMenuItem tests pass
