Previously the client cached open session tabs in localStorage and resurrected any that the server no longer knew about as grayed-out "ended" stubs. On multi-device use (close tab on mobile, open desktop) this left stale phantom tabs the user had to manually dismiss. Remove _restoreEndedTabs / _saveTabMetadata, the session._ended branch in selectSession, the data-ended render attribute, and the matching CSS rule. Clear the legacy localStorage key on init to purge stale entries. Co-authored-by: Teigen <teigen@TeigendeMac-mini.local>
