The SystemVerilog class-body field regex in _augment_systemverilog_semantics
matched only unqualified `<type> <name>;` declarations. Its `^\s*` prefix
consumes leading whitespace but not leading class-property qualifiers, so a
qualified field such as `rand Config m_cfg;` (three tokens) failed the
two-token shape and its type reference was silently dropped from the graph.
Consume optional leading qualifiers (rand/randc/local/protected/static/const/
automatic/var) before the type token. Zero qualifiers preserves the existing
behavior; the type and name capture are unchanged.
Adds test_systemverilog_qualified_field_references plus rand- and
protected-qualified fields (and a Config class) to the shared .sv fixture.
