Both Node::Ident and Word carried a highlight_override field, and both were dead — the walker driver discarded the Ident's and walk_word hardcoded Keyword. So column types (int, serial, …) rendered identically to table/column names. Wire both overrides through, and add a dedicated HighlightClass::Type with its own theme colour (tok_type), distinct from keyword-purple and identifier-teal. The three type Ident slots opt in, so canonical types and the advanced-mode single-word SQL aliases (float, varchar, …) render as types; the two-word `double precision` alias opts in via a new Word::type_keyword constructor.
