v1.13.5

Added

• Focus misses now hint where to look. When focus_method or
  focus_multiple_methods returns NOT FOUND and the file's type is partial,
  the response notes the member may be in a sibling file in the same
  namespace/folder; when the type has a base list, it notes the member may be
  inherited and points at the base type's file. Turns a bare NOT FOUND into an
  actionable next step instead of a dead end.
