Module spinner 

Braille spinner used while a turn is in flight.

Goal-144 introduces a single-line spinner rendered transiently at the bottom of the transcript while crate::tui::app::TurnState::running is true. The animation frame is driven by a counter in crate::tui::app::App::spinner_frame that the main loop ticks every draw cycle.
