Quitting a desktop app on Linux or Windows can leave the IDE showing it as running

Quitting a running desktop app through its File > Quit menu item (or any app-initiated quit) closes the app's windows, but Objo Studio keeps showing the project as running. The Run/Stop toolbar and debugger UI stay live, and the IDE does not return to idle until the user presses Stop. The app itself looks like it exited, which makes this look like an IDE glitch rather than a hung process.

Expected behaviour: quitting the app exits the process, the debugger session ends, and Studio returns to its idle state automatically.

This reproduces on Linux and Windows. On macOS the same quit path exits cleanly, so the impact is limited to the in-window menu bar used on Linux and Windows.
