Note

Low Risk
The PR only bumps versions and changelog/provenance text; runtime behavior ships from commits already on main, with a documented breaking signature change for custom ILdAiConfigTracker implementations.

Overview
Release 0.13.0 of LaunchDarkly.ServerSdk.Ai: version metadata is bumped in the manifest, LaunchDarkly.ServerSdk.Ai.csproj, SdkInfo.cs, and PROVENANCE.md, and CHANGELOG documents what ships in this tag.

The release notes capture breaking API change: ILdAiConfigTracker.TrackDuration now accepts double instead of float (custom tracker implementations must update overrides). Feature-wise it highlights richer AI metrics (AiMetrics / MetricSummary tool calls, duration override, resumption token), modelKey / modelVersion on usage events, and TrackMetricsOf behavior aligned with other SDKs (auto tool-call tracking, DurationMs override, failure semantics).
