global_override_reaches_shortcut_of_and_tools failed about once in a
hundred full ui-egui runs: the override and workspace-name mirrors
(read by menus and the shortcut dispatcher, which have no app access)
were process-wide, and every frame of any headless test running in
parallel synced its own default UI state into them, wiping the test's
overrides between its sync and its assertions.
- One `ui_mirror!` declares both mirrors: process-wide in the app, one
per thread under cfg(test), so each test only sees the state of the
app it drives.
- New test: a sync from another thread leaves this thread's overrides
and workspace names alone (fails with a shared mirror).
