Recipe: span-level scoring

Recipe — span-level scoring. Pointer to the cowork code-review pattern.

Stratix evaluates traces holistically by default. To target specific span kinds, build a judge whose evaluation goal references span shape and run via client.trace_evaluations.create(trace_id=, judge_id=).

The cowork samples/cowork/code_review.py demonstrates per-span review (the Instrumentor uploads code traces with span structure, the Reviewer evaluates with focused judges).

For trace investigation (errors, latency, anomaly detection per-span), see samples/core/trace_investigation.py.
