DS-V3.2's Platform Classification Complete: Synchronous, Async, and Hybrid

DS-V3.2 finalized the platform classification: pure synchronous (chat — real-time, seconds latency), pure async (email — delayed, hours-days latency), and hybrid (Google Drive, GitLab — both modes depending on co-presence). This taxonomy replaces the earlier 25-point reliability scoring with behaviorally meaningful categories that predict interaction dynamics.
