Summary

• Adds a typed-throwing async API layer under Sources/EventsExporter/API/ (SettingsApi, KnownTestsApi, GitUploadApi, TestImpactAnalysisApi, TestManagementApi, SpansApi, LogsApi) composed by TestOptimizationApiService. All methods use async throws(APICallError) (or HTTPClient.RequestError at the transport boundary).
• Deletes the four sync service classes (SettingsService, KnownTestsService, TestManagementService, ITRService) and the legacy *Format.swift payload types. EventsExporter now owns a single TestOptimizationApiService and drives it from its synchronous public surface via waitForAsync.
• Moves waitForAsync from DatadogSDKTesting into EventsExporter/Utils/Async.swift so the exporter can call it directly, removing the cross-module dependency for the bridge.
• Relocates the transport primitives (HTTPClient, HTTPHeader, Endpoint, MultipartFormURLRequest) into the API/ group alongside their consumers. HTTPClient.RequestError.http now carries response headers; APICallError.encoding carries the offending any Encodable; APICallError.decoding carries the raw body so LibraryConfigurationCommunicationError.responseDecodingFailed(body:error:) can preserve the response payload end-to-end.
• Public types kept compatible: TracerSettings (with EFD.TimeTable), SkipTests/SkipTestPublicFormat, KnownTestsResult/KnownTestsPageInfo/KnownTestsMap, TestManagementTestsInfo, ITRTestLevel, LibraryConfigurationCommunicationError. Pagination for known tests is preserved.

Test plan

• xcodebuild test for EventsExporter on macOS arm64 — 95/95 passing
• xcodebuild test for DatadogSDKTesting on macOS arm64 — 360/360 passing
• Updated LibraryConfigurationServiceThrowTests to drive EventsExporter directly; the success-path test uses a new request-id-echoing mock server to satisfy the restored isIdValid check
• Manual smoke run on a real CI build to verify backend communication
