The tab context menu's bulk closes did nothing, and the pin item was labelled with an icon's name. Both are fixed here, each with the test that proves it.

Why the closes did nothing

useTabs refreshed its tab list only when the router's location changed. But every one of these actions writes the list through URLTabSyncEngine.updateURL, which changes the URL with history.replaceState — something React Router never sees. So:

• Close Other Tabs / Close Tabs to Right / Close Tabs to Left wrote the new list to the URL, left the hook holding the list it started with, and the tabs stayed on screen. The action looked like it did nothing.
• Only the two actions that also navigated appeared to work — Close All Except Pinned, and closing the active tab — because the navigation is what refreshed the list.

The hook now follows the engine's own notifications, which fixes the whole family at once. Pin and unpin were stale for exactly the same reason, which is why they are in this PR.

Close Other Tabs also navigates to the tab it kept, so the page follows the tab that became active instead of showing a tab that is gone — which is what you were doing by hand ("i cant close other tabs without navigating inside them").

The pin item

It carried the icon's name as its label — MapPinIcon Tab — the same class of leak the tab titles were already fixed for, and unlike every other item it left the menu open over the tab it had just changed. It now reads Pin Tab / Unpin Tab and closes the menu.

Verified

• src/hooks/tabs/__tests__/useTabsBulkClose.test.tsx (new) drives the real hook over the real engine for the five closes, and mounts the three tabs the URL describes. Written first and watched fail: 4 of the 6 failed before the fix — the tab list simply did not change.
• The pin item's label and its menu closing are covered in TabLabelRendering.test.tsx, which already guarded against icon names leaking into labels.
• 264 tests pass across src/hooks/tabs, src/services/tabs and src/components/tabbedWorkspace.

Not in this PR

Two things I noticed while working and deliberately did not chase here:

• Duplicate Tab and Open in New Window leave the menu open too. They act correctly; only the menu's dismissal is inconsistent. Same one-line shape as the pin fix if you want it.
• The browser console reports Index creation warning for app_settings: no such column: "[object Object]" on first run — a real defect in index creation, unrelated to tabs.
