Go-to-token context menu on metadata grid

Right-click on a [Kind=Token] cell now exposes a "Go to token" menu item
that reuses the same NavigateToCellRequested path as the hyperlink-style
left-click. Visibility is gated on the click landing on a token-kind
column, so plain columns and non-metadata grids stay clean.
