marshal-tui 0.9.0

Terminal UI for the marshal coordination daemon — live roster + message stream.
marshal-tui-0.9.0 is not a library.

marshal-tui — terminal dashboard powered by a MykoClient.

Connects to the daemon as a passive observer (no Session item is created — peers don't see the TUI on the roster), subscribes to live GetAllSessions and GetAllMessages queries via hyphae cells, and renders the result with ratatui.
