ConversationListView (advanced list, ⌘L): ⌘-click toggles a row,
Shift-click selects a contiguous range, and a "Move to Folder"
toolbar button/context-menu entry moves every selected conversation
at once. Confirmed working live.
SidebarView: same capability, adapted to the sidebar's own click
model since opening a chat there previously required only a single
click. Single-click now selects only (replacing the prior selection),
⌘/Shift-click work the same as the advanced list, and double-click
opens a chat (clearing the selection). Selected rows get a distinct
neutral tint from the existing accent highlight used for the
currently-open conversation. Dragging a row that's part of a
multi-selection now bundles every selected conversation's ID into the
drag payload, so dropping on a folder moves the whole selection
instead of just the dragged row.
Range-selection math (idsInRange) is defined once on
ConversationListView and reused directly by SidebarView rather than
duplicated — it's `internal`, not `private`, specifically so both
views can share it.
