fix(native): windows 0.61 API paths — repair the CI Windows compile

Four unresolved-import/type errors from the release build (first real compile):
- toast.rs: generic IMap moved to the windows-collections crate; read the reply
  from the ValueSet returned by UserInput() directly (HasKey/Lookup are exposed
  on the class).
- jumplist.rs: PROPVARIANT lives in Win32::System::Com::StructuredStorage (not
  windows::core); IObjectArray/IObjectCollection in Win32::System::Com (not
  UI::Shell); PKEY_Title in Win32::Storage::EnhancedStorage (feature added);
  build the title PROPVARIANT via From<&str> (VT_LPWSTR).
- smtc.rs: event registrations return a plain i64 token in windows 0.61 (the
  EventRegistrationToken newtype is gone).
- thumbbar.rs: HICON was imported inside the fn body but used in its signature —
  fully qualify the return type.
