MarkLens 1.0.1

The five-second close on Windows, fixed. Linux was never affected. Both installers, the portable zip, the .deb and the AppImage are below with SHA256SUMS.

Fixed

• Closing the window on Windows took over five seconds, with the window
  still on screen the whole time. The Flutter template's FlutterWindow
  destructor lets its engine controller die as a plain member, and a
  unique_ptr destructor does not clear the pointer first — so messages
  arriving during the teardown were handed to a half-destroyed engine. The
  template's WM_DESTROY path nulls the pointer explicitly; the plugin call
  the shell left by (window_manager.destroy(), a bare PostQuitMessage)
  skipped that path. The destructor now resets the pointer itself, and the
  shell leaves by close() so the stock path runs. Measured on the reference
  machine with tool/exit_timing/measure_exit.ps1: 5.1–5.9 s before, the
  window hidden at ~90 ms and the process gone at ~120–180 ms after
  (doc 03, "App exit").
• Exit is now an explicit, bounded sequence (doc 03): write everything, ask
  the watchers to stop and wait for them within a bound, release the
  single-instance lock, hide, close. A step that does not answer is named in
  the diagnostic log and the exit goes on; nothing on disk depends on it.
• A setting changed in the quarter second before exit was lost. Doc 05 said
  disposal flushed it, and nothing disposed anything on the real exit path.
• The watchers were never asked to stop on exit; on Windows each is an isolate,
  and one nobody asks is torn down by the VM instead. Now asked, and awaited.
• Two clicks on the close button started two shutdowns. A second close now
  joins the first.
