fix(r8): silent-handler ratchet compliance in fault seam — log instead of pass

The two catch-all handlers added in dac6e97 (r8_fault.record evidence
write, notify_event_bridge seam probe) tripped the #126 silent-handler
ratchet (S110 75 -> 77), which cascaded to the lint-baseline contract
test. Both handlers now log to stderr/stdout and continue — the seam
stays fail-open but is no longer silent. S110 back to 75=75.
