1ce6b9c made closing stop the session first, which was right and incomplete: the stop path opens TWO
modals, and WPF forbids that during a close. The creator's #2 test produced it immediately —
System.InvalidOperationException: Cannot set Visibility to Visible or call Show, ShowDialog, Close,
or WindowInteropHelper.EnsureHandle while a Window is closing.
Two prompts are suppressed by a `_shuttingDown` flag, each taking its safe default rather than a prompt
nobody can answer:
- The rename dialog: the recording is saved under its automatic name. Never discard footage the creator
did not choose to discard.
- The private-broadcast keep/delete prompt: the broadcast is KEPT (stays private on YouTube) instead of
being deleted by an answer that was never given.
The general rule this establishes: a teardown path may not ask questions. Any future prompt reached from
stop must check IsShuttingDown.
Not covered by a unit test — the trigger is a real WPF close, not reachable from the view model. Verified
against the exception in %APPDATA%\ytLlive\startup.log (09:40:27) and it needs the creator's retest.
