Example: Memory with Tracing

This example demonstrates how to use memory with context tracing enabled.
When tracing is enabled, memory operations (store/search) emit trace events
that can be used for debugging and analysis with the LLM Judge.

Usage:
    python memory_with_tracing_example.py

To judge the trace:
    praisonai recipe judge <trace_id> --memory
