fix(tests): Update simulator/debugger failure assertions to new output format

The output standardization refactor (b6bde24) strips known prefixes
(e.g. 'Install app in simulator operation failed:') inside buildInstall/
Launch/StopFailure and renders the header as 'Failed to install/launch/
stop app.' with the raw diagnostic under 'Errors (N):'. Update the stale
assertions in install/launch/stop_app_sim and debug_attach_sim tests to
match the rendered text, keeping the diagnostic-bullet assertions intact.
