"""Tests for the run view (ui/runview.py) — the conversion status screen.
The view is driven the same way as the other TUI widgets: the fake curses
module and recording screen from test_tui stand in for a terminal, the
worker/monitor threads are stubbed, and events are fed through the view's
own queue to exercise state transitions, rendering, and the Esc/q
cancel → stop-server flow.
