feat(memory): configurable background memory update notifications

Background memory reviews now support three notification modes,
configured via display.memory_notifications in config.yaml:

  off     — no chat notification (still logged to stdout/HA log)
  on      — generic '💾 Memory updated' (default, unchanged behavior)
  verbose — content preview with action indicators:
            💾 Memory ➕ Hermes Repo liegt unter /config/amy/hermes-agent/...
            💾 Memory ✏️ Updated repo path from claude-code to hermes-agent...
            💾 Memory ➖ old entry about claude-code path...

Previews are truncated to 120 chars for adds/replaces, 60 for removes.
Each action gets its own line in verbose mode for readability.
