refactor(code-graph): remove unused options/setOptions props

CodeGraph now manages options locally instead of receiving them from
App. Remove the dead props from the interface and stop passing them
from App.tsx. The Combobox inside CodeGraph fetches options on its own.

Addresses typo-app review comment about local state shadowing props.
