fix(tooltip): don't reopen on window/tab refocus (#1800)

[effinrich]

Summary

Fixes #1800. A Tooltip whose trigger is focused reopens itself when you switch away from and back to the browser tab (or minimize/restore the window).

Root cause

Returning to the tab refocuses the previously-active element, firing a synthetic focus event on the trigger. TooltipTrigger's onFocus opens on any non-pointer focus, so it can't distinguish that refocus from a genuine keyboard focus — and opens the tooltip.

Fix

Track window blur via a ref (mirrors the recently-merged window-blur handling for menus, #3938). When the trigger is focused immediately after the window was blurred, treat it as the tab/window regaining focus and skip opening — consuming the flag so the next genuine focus opens normally.

Test

Adds a regression test using window.dispatchEvent(new FocusEvent('blur')) then fireEvent.focus(trigger), asserting data-state stays closed, and that a subsequent genuine focus still opens. Changeset included (patch: @radix-ui/react-tooltip, radix-ui).

Tradeoff (open to feedback)

If the window is blurred and the user later keyboard-focuses a different, never-focused trigger, that trigger's first focus is suppressed once. Minor — happy to switch to a requestAnimationFrame-on-window-focus reset to eliminate it if preferred.
