Rename from another tab's menu stored only a boolean that the
session-switch reset effect wiped before the menu finished closing, so
the tab activated but rename never began. The pending rename now
carries the target session id and begins exactly when that session
becomes active (whether the menu closes before or after the switch),
without the reset effect cancelling it — and without an in-flight
rename being cancelled by unrelated re-renders. Tab background/text
state changes animate at 75ms so activation reads immediate.
