Make the command center stable and workspace-aware (#2749)

* feat(app): expand command center actions

Keep command center navigation stable by revealing only clipped rows without smooth centering. Prioritize a concise default list while making workspace, Git, pane, and creation actions searchable through the existing contribution and action-policy paths.

* test(app): search for query-only command action

Add project is intentionally absent from the unfiltered command center. Exercise the overlay flow through search before selecting it.
