ChatBuffer now has get_message(), get_formatted_message(), and view_item()
so repeat_item, copy_to_clipboard, and view work correctly with chat
messages. open_conversation (Ctrl+Win+Alt+C) detects chat buffers and
delegates to view_chat(). Opening a chat buffer now announces its name
and item count for screen reader feedback.

Replicate the Mastodon pattern where conversation buffers are inserted
as children of the direct_messages node, making Chats expandable in the
tree. Also adds duplicate detection and auto-navigation to existing
chat buffers.
