Note

Medium Risk
Breaking public API on ILdAiConfigTracker affects custom implementations; metric/tracking behavior changes can alter billing and observability data.

Overview
Release Please bumps LaunchDarkly.ServerSdk.Ai from 0.12.0 to 0.13.0 across the manifest, .csproj, SdkInfo, provenance docs, and CHANGELOG.

The new 0.13.0 notes (already landed on main, not in this diff) expand AI metrics tracking: optional ToolCalls and DurationMs on AiMetrics, richer MetricSummary (tool calls + resumption token), and TrackMetricsOf behavior aligned with other SDKs (auto tool-call tracking, duration override, clearer operation vs extractor failures).

Breaking: ILdAiConfigTracker.TrackDuration now takes double instead of float — custom tracker implementations must update their override.
