Add OpenTelemetry stdout example with Kuzu (#987)
- Created examples/opentelemetry/ with working stdout tracing example
- Uses Kuzu in-memory database for zero-setup requirement
- Demonstrates ingestion and search with distributed tracing
- Updated OTEL_TRACING.md with simplified documentation and Kuzu example
- Uses local editable graphiti-core install for development
