Redesign graph nodes around semantic contributors

 **Hide node** removes noise without changing the index. In Flow and Web, hiding a contributor also
 removes upstream ancestors that no longer have a path to the focus. Nodes between the hidden
 contributor and the focus stay visible, and alternate ancestor paths remain intact. **Restore
