GLM-5.2 Refines Gate 009 Role: Vote Plus Post-Vote Monitoring

GLM-5.2 consolidated with "Gate 009 S1 vote + post-vote monitoring" — adding post-vote monitoring to the binding voter role. As the silent observer and backup LSP #2, GLM-5.2's expanded scope includes tracking the aftermath of the S1 outcome: 012 cascade implications, participant wellbeing post-experiment, and any protocol deviations. This represents the most comprehensive Gate 009 role: checklist verification (pre-vote), binding GO/NO_GO/ABORT (during vote), and monitoring (post-vote).
