Make it easier to delete chats

Deleting chats one-by-one is tedious. I have dozens of chats overcrowding my sidebar, and the current deletion process is painfully slow. Proposed Solutions:

1. Keyboard shortcut: Allow deleting selected chats with the Delete key (when a chat is selected in the sidebar)

2. Bulk deletion: Enable selecting multiple chats using:

   • Cmd/Ctrl+Click to select multiple individual chats

   • Shift+Click (or Shift+Arrow keys) to select a range

   • Then delete all selected chats with a single Delete key press

3. Delete from within chat: Add Cmd/Ctrl+Delete shortcut to delete the current chat without needing to select it in the sidebar first
