Note

Overview
Release Please bumps LaunchDarkly.ServerSdk.Ai from 0.12.0 to 0.13.0 in the manifest, csproj, SdkInfo, provenance docs, and adds the 0.13.0 changelog section.

That release (already merged via prior commits) expands AI metrics and tracking: optional ToolCalls and DurationMs on AiMetrics, accumulated ToolCalls and ResumptionToken on MetricSummary, modelKey / modelVersion on usage events, and TrackMetricsOf behavior aligned with other SDKs (auto tool-call tracking, duration override, failure semantics).

Breaking: ILdAiConfigTracker.TrackDuration now takes double instead of float — any custom tracker implementation must update its override.
