Align the pure-Rust Windows translation, chat, settings, and toolbar design with macOS using shared Lucide icons. Fix hover and scrolling repaint artifacts, dropdown alignment, and native model download folder selection.
Persist manual service stops, cancel active built-in requests, and add confirmed cleanup of built-in models and managed runtime dependencies. Cover lifecycle behavior with Rust tests and add a native Windows repaint regression harness.
Validation: native Windows release build and installed UI verification; isolated Windows service lifecycle checks; six model manager tests; macOS cargo check; git diff --check.
