NavigateCellEvent class

Navigates focus to an adjacent cell, with optional path extension.

• extend = false (plain arrow): resets the path to [newCell].
• extend = true (Shift+Arrow): appends the adjacent cell, or pops the last cell when moving back along the existing path (shrink selection).

Falls back to row-level navigation (up/down only) when no cell is active.
