Subject: [PATCH] feat(navigator): add currentTabCode + currentFilter to UI
 store (P2 prep)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

setTab(code) atomically updates currentTabCode and resets currentFilter
to '' — switching tabs starts a fresh search context. setFilter(value)
updates only the filter — the user is typing in the same tab.

TDD: 3 new cases (16 total in navigatorUiStore.test).
