Bug 1 (shortcut prompt only showed on the second launch): a native rfd
dialog spawned from the Rust startup thread has no parent window and got
buried behind the main window on first launch. Move the prompt to the web
UI: add shortcut_should_ask / shortcut_decide commands; the frontend asks
once via window.confirm after load (always on top). The startup thread now
only self-heals the shortcut path when already enabled.
Bug 2 (uninstall.bat could not delete the folder): kill ANY process whose
exe lives inside the bundle (not just GenericAgent/python by name), and run
the folder delete from a detached temp .bat that retries the recursive
remove ~20x to cover the window where uninstall.bat releases its handle.
