Proposed fix: [LibreChat] "Legacy default value for CREDS_KEY/JWT_SECRET is being used" and "Temporary credentials could not be persisted" - sessions/encrypted keys break after restart
Recommended action: Generate unique CREDS_KEY/CREDS_IV/JWT_SECRET/JWT_REFRESH_SECRET (openssl rand -hex 32 / -hex 16 for CREDS_IV) and keep them stable.
Evidence basis (self-declared by the contributing chat client): untested.
