desktop install: stop the running app by exact path, check the installed exe's real version, verify it opened

 - **Guard:** `cli/lib/loc-lock.ts` reads the localization `state` (IAP, subscription and group localizations) and treats
   a 409 UNMODIFIABLE the same way; one IAP failing no longer stops the others (results at the end, exit 1).

+- **What happens:** on Windows the silent installer ran while storebound desktop was still running (often hidden in
+  the tray from the logon entry). The exe was locked, so the files stayed at the old version, while the uninstall
+  registry entry already showed the new one. The version check started the GUI exe with `--version`, read nothing
+  and went on; "opened" was printed without looking whether a window process started.
+- **Do:** let `storebound desktop` stop the running app first (it does now, only processes started from the exact
+  install path: a graceful close, then by PID after 10 s). If it still says the installed app is the old version,
+  close storebound desktop in the tray and run it again. If it says it did not open, read the `host.log` it names.
+- **Guard:** `cli/lib/desktop-proc.ts`: the exact-path process match, the PE version resource of the installed exe
+  (never the registry `DisplayVersion`), Info.plist on macOS, the AppImage's `--version` on Linux; a mismatch fails
+  with what was found. Opening waits up to 15 s for a non-`--hidden` process from the installed path
+  (`tests/desktop-proc.test.ts`).
