Session Persistence Deduplication

What: Fixed duplicate session log entries when fetching history

Issue: When resuming sessions, the same entries could be persisted multiple times

Fix: Added UUID tracking per session to skip already-fetched entries

Impact: Cleaner session history, reduced storage overhead, faster session loading

Evidence: New deduplication check at start of F8B() function at line 397200 in v2.0.0
