[Bug] OTEL data missing COST_USD field in API request events (v2.1.122+)

Bug Description
Note that we see this across our telemetry data.
Claude Code client versions 2.1.122 and newer stopped emitting the COST_USD field on API request events. Token counts and model names still come through fine - only the cost field is NULL.
