v0.3.3 — minimize the transfer dialog to a floating chip (keeps running)

- Submit/Get-Latest progress dialog can be minimized to a small bottom-right
  chip (like the .sln build chip). Shows op + N/total + % + a thin progress bar;
  click to expand. Submit keeps a Cancel button on the chip.
- The transfer runs in the backend regardless, so minimizing never interrupts it.
