fix: update installer never ran, app closed without updating (1.2.6)

The installer was spawned with DETACHED_PROCESS, which makes the
host process exit as soon as it starts, so the script body never
executed: no log, no file swap, no restart. Only CREATE_NO_WINDOW
is needed to keep the window hidden.

- stop both the bootloader and the Python child of a onefile build
- verify the script process is still alive before quitting the app
- write logs to updates/logs and always relaunch on failure
