The previous commit added the cadence rule and left `make all` red: the
gate-registry self-tests expect exactly one finding each, and their
fixture gates declared no cadence, so they got two. I committed without
re-running the gate to the end.
Fixtures now declare a cadence, and the rule has three controls of its
own: a cadence=all gate absent from `make all` is caught, a gate with no
declared cadence is caught, and declaring `manual` clears it — without
that last one the rule would fire on every manual gate.
