Note

Low Risk
The PR only changes release metadata; functional risk is for consumers upgrading to 0.13.0, mainly the breaking TrackDuration(double) contract on custom ILdAiConfigTracker implementations.

Overview
Release Please PR that bumps LaunchDarkly.ServerSdk.Ai from 0.12.0 to 0.13.0 across the manifest, .csproj, SdkInfo, provenance docs, and a new 0.13.0 changelog section.

The code in this diff is version/metadata only; the release notes describe what ships in 0.13.0: richer AI metrics (AiMetrics / MetricSummary with optional ToolCalls, DurationMs, ResumptionToken), modelKey and modelVersion on usage events, TrackMetricsOf behavior aligned with other SDKs (auto tool calls, duration override), and a breaking change—ILdAiConfigTracker.TrackDuration now takes double instead of float (custom tracker implementations must update).
