[ReasoningBank] AgentDB not available, using in-memory mode

Error message

[ReasoningBank] AgentDB not available, using in-memory mode

What it means

Log warning in initialize: AgentDB (with HNSW persistence) is unavailable, so the ReasoningBank runs in pure in-memory mode — patterns are not persisted and searches are in-memory scans.

Solutions

1. Install/enable AgentDB for persistent pattern storage; in-memory mode loses patterns on restart.
