deps: upgrade ink from 6.2.0 to 6.8.0

Upgrade the Ink terminal UI framework to the latest version.

Code changes required for compatibility:
- Pass concurrent: true to inkRender() (new default behavior in 6.8.0)
- Defer unmountInk() calls with setImmediate() so React 19 can flush
  batched state updates before the component tree is torn down
- Adapt waitUntilExit() return type change (.then(() => {}))
