The prior commit only documented the <=2-member DM auto-classification
in the adapter.py module docstring — source an operator configuring
MATRIX_REQUIRE_MENTION etc. would never read. Issue #114733 explicitly
asks for the callout wherever MATRIX_ALLOWED_ROOMS,
MATRIX_FREE_RESPONSE_ROOMS, MATRIX_REQUIRE_MENTION, and MATRIX_AUTO_THREAD
are documented for operators, i.e. the env-var reference table and the
Matrix user guide. Add the same rule + bypassed vars + escape hatch to
both, matching the precedent set by 08aa67e473 for this kind of env-var
clarification, and extend the doc-content test to cover them.
