Document the hippocampus-inspired design (episodic + associative memory,
background consolidation agents, neuroscience-inspired replay/spectral

levels, activity-aware thresholds, IRC/Telegram modules). Fix config
format to match reality (JSONL, not TOML). Update instructions.md in
the store with notification commands.
