fix: close a gap in the H3 disable pass — output_guidance snapshot and DynaShift capture

Both were captured "regardless of the toggle" by original design (so
turning guidance on later works immediately), which meant they kept
running on H3 even after output_guidance/dynashift were forced off —
exactly the kind of function the "disable everything unrelated to
REINS" pass was supposed to catch, missed because the capture point
predates any toggle check.

Confirmed live: the user's own log showed "DynaShift negative bank
updated — 1 entry" after the rest of the disable pass had already
landed.
