The Archived sessions intro told users to Ctrl/⌘-click a chat in the sidebar to
archive it. That gesture opens the chat in a new tab: resolveSessionRowClick maps
⌘/⌃-click to 'newTab' and only ⌥+⇧-click to 'archive'. Anyone following the copy
never archives anything, and that line is the only in-app hint the gesture exists.
Swap the modifier in the six locales carrying the string, keeping each
translation's wording. The resolver and the row's own comment already document
⌥+⇧ — only the user-facing copy was stale.
