Sentry Span Streaming Migration (Python)

Migrate from the default transaction-based trace lifecycle (static) to span streaming (stream), where spans are sent individually as they complete instead of being batched into a transaction at the end.

This skill covers the Python SDK. For JavaScript, see Span Streaming (JavaScript).
