BFlatandClaude Opus 5.5 b97a72ac79 File dialogs no longer freeze or crash the app (#673, #574) (#1071)
* File dialogs no longer block the event loop (#673, #574)

Open, Save As, Export As, Place and every other file dialog ran
rfd's synchronous dialog inside winit's event handler. On macOS that
runs AppKit's modal loop there, and an event arriving meanwhile
aborted the app (SIGABRT, panic_cannot_unwind); on Linux the frozen
event loop made compositors offer to kill the app.

The platform shell now shows dialogs through one asynchronous
Services::file_dialog: the request is queued with what to do with the
answer, shown at the end of the frame with the window as its parent
(a sheet on macOS, an owned modal dialog elsewhere) and awaited on a
helper thread; the answer comes back through a channel that wakes the
app, which continues the action on a later frame. One dialog at a
time. The unsaved-changes prompt waits behind Save's dialog and closes
the document only once it saved. The web build uses the same service.

* brush picker: Import ignores the Open dialog's result, like the other callers
