DBMS-specific enumeration overrides (plugins/dbms/<dbms>/enumeration.py),
driven through each full DBMS handler with the injection layer mocked, so the
dialect-specific table/column discovery paths run without a live target. The
in-band (UNION/error/direct) branch is taken via conf.direct=True and
inject.getValue is stubbed with canned result rows.
