"""
Memory interface for Clawdbot runtime integration.

This module provides the bridge between Clawdbot (Node.js) and the
Python memory system. It can be used in three ways:

1. CLI mode: Called as subprocess from Node.js
   python memory_interface.py search "query" --guild 123 --limit 5
   python memory_interface.py context "message text" --guild 123 --user 456

2. JSON-RPC mode: Run as a simple server
   python memory_interface.py serve --port 9876

3. Direct import: From other Python code
