Main's rewritten test_tui_npm_install.py tests call _make_tui_argv expecting the Ink/npm flow unconditionally; with the dual-engine dispatch merged in, _resolve_tui_engine() auto-selects opentui whenever ui-opentui/dist is built in the repo, routing the call away from the path under test (first subprocess became 'node --version' instead of 'npm run build'). Pin the engine to ink via an autouse fixture, mirroring the existing pinning precedent in test_tui_resume_flow.py.
